Ruby managed to cheer Robin a little but somehow she gets sick all of the sudden. She's not the only one who catches the flu but also M'gann as well.

"You look better." Artemis commented to see Robin is getting better than last night.

"I feel better." Robin spoke up and stared at the two girls. "I'm sorry, Me- Dawn and Davina. I hope you didn't catch it from me."

"I'm sure it doesn't have to do with my magic last night." Ruby answered weakly and her vision are blurry. "I was okay until I'm getting ill so quickly." Wrapping herself using the blanket and shivering from the cold. The scarlet-haired girl rarely gets sick not until she used a lot of magic.

"Here." Artemis grabs another blanket and wrapped around Ruby. "You're shivering a lot."

"Ye-yeah..." Chattering her teeth and Artemis didn't hesitate to hug the girl. "Warm..."

"I feel so silly." M'gann groaned. "Who knew a Martian could be vulnerable to a human virus?"

"Uhh... H.G Wells?" Robin suggested and giving Ruby a herbal tea to warm her body. "Look, when did you girls first feel sick?"

"Just after boarding the train... it came on suddenly." M'gann answered.

"Me too." Ruby blows her drink gently before drinking it slowly. "I only get sick if I used a lot of magic to summon my spirits."

"Same with me, the other night." Robin spoke up and pointing himself. "I remember Ray rubbed my head for good luck right before we went on."

"Ray? That roustabout?" Conner asked the boy wonder curiously. "He touched her before we boarded. That guy must be a walking petri dish."

"He helped me to carry the luggage and patting my head." Ruby spoke up and finished her drink. "Saying a girl like me shouldn't carry heavy stuff. There's something odd about him."

Robin didn't say anything but walked out of the room. Ruby sighs heavily and shook her head. She didn't want to be left behind and letting them pursue the mission without her. The scarlet-haired girl followed them and Robin stopped her.

"You should stay in bed, Davina. You were shivering a while ago." Robin spoke up softly and Ruby shook her head.

"No, my boyfriend once said to me, 'I'll manage'." She smiles softly. "I hate being alone and waiting for myself to fully recover." Robin sighs quietly and respects her wishes before she gets angry. After all, he prefers his shy Ruby than anger Ruby.

Everyone silently goes inside of Ray's room and didn't see him at all. "I guess he wasn't THAT sick." Conner spoke up bitterly.

Roy observes the elephant crate in front of him. "Does this circus have an elephant I don't know about? I knew the pipsqueak has tiger spirit."

"This pipsqueak has a name..." Ruby muttered bitterly under her breath and M'gann patted her head.

"Not on foreign tours..." Robin answered and ignoring Roy's last part of calling his girlfriend pipsqueak.

Roy opened the crate. "Empty. No, wait!" He peered down the crate closely and wipes it to look closely. "Ash..."

"The warehouse fire in Bruges!" Robin exclaimed and starting to connect the dots.

"Uh... guys!" Artemis called them and Ruby cringed in disgust. "I found Ray." She's holding Ray's face mask.

"Split up! Search the whole train!" Robin ordered them.

"Dane, Dean, Diane, Davina, come in!" Ruby heard Robin's voice in a hushed tone. "We're chasing someone who's stolen 'Dawn and Davina's act'. Their whole shtick, if you catch my drift." Her emerald eyes widened in shock. Whoever this Ray is, he can copy their ability which means he copied M'gann's ability and her lost magic crystal.

"I got him. But he's on to me. Exiting the dining car now." Conner informed them. "He's gone top side."

"I'm close to your destination, Dean." Ruby spoke up and opened the door. "I'm on my way." She groaned and shook her head. "Not now..." The scarlet-haired girl jumps and grips the handle before pushing herself up.

"That won't work on me clown." She heard Conner's voice.

"Davina." Ruby turned around to see Robin's worried expression.

"I'm fine..." She assured him and stared at the clown. "God, I hate clowns." Ruby gulps and swallowing her fear of clowns.

"That's no clown, he's the Parasite!" Robin informed them. "The guy who once stole Superman's powers."

"As if you, kids, are who you claim to be..." Parasite spoke up with a smirk on his face. "Please..." His appearance changed into a dark purple.

"Stay out of his reach." Robin warned them. "There's no flu going around. The weakness comes when he makes physical contact. And feeds on the powers and abilities of the others."

"This is going to be a tough battle." Ruby muttered with a grim look on her face. "It also explains why we're feeling ill all the sudden."

"I happen to be a bit of glutton today." Parasite spoke up with a dark look on his face. "Chowed down on the skills of nearly every loser in this troupe... but, oh, my. But the Piéce de résistance was Dawn and Davina Danger or whatever their real names are." Ruby is glancing behind her to see M'gann and the others are joining them. "Thought I'd pouch on Dawn's trapeze skills and Davina's taming the tiger. Imagine my surprise when Dawn's tasted like Martian Manhunter, instead. When I also tasted Davina, she has the unique abilities of her crystals." Ruby's shoulder begins to tense and glaring at him coldly. "Both of them made a lovely appetizer. But guess who I want for my entrée." Using telekinesis to pull Conner and grabbing his neck. Conner is gasping in pain. "M-hmm..., now that's the full body of Kryptonian. A flavor I love."

"Everyone stay, whelm!" Robin informed them. "Subdue, but keep your distance!"

Ruby is biting her lower lips angrily. "I can't summon my spirits or using star dress magic." She spoke low enough for M'gann and Robin to hear. "I'm glad he managed to copy my crystal magic, not my celestial magic."

Artemis and Roy readied their weapon and Parasite uses heat vision to burn the bows. "You know, I almost never say this... but I'm sated. Hate to eat and run... " He flew with the crate. Robin jumps at the top of the crate and about to stop Parasite. "Sorry... no hitchhikers." Swinging his arm at Robin.

"Robin!" Ruby grabs his hand before Robin could fall off the train. "Uh..." Struggling to pull him up due to her weakened state.

"Here!" She sees three hands as Artemis and Roy helped the scarlet-haired girl.

They pull Robin up and M'gann approached the clone. "Conner! You alright?"

Conner stands up while closing his eyes. "Fine, fine!" He assured them.

Robin stands up as the others approached M'gann and Conner. "You're drained!" The boy wonder exclaimed. "Parasite took more power than you even have! Heat vision?"

"I have the genetic potential for it!" Conner snapped at him angrily. "Must've been enough for him."

"Hey!" Ruby exclaimed and looked shocked to see his aggressiveness. "There's no need to bite his head off or anyone. He was just asking." She defended his boyfriend and stumble a bit when a wave of dizziness hit her.

"You need to call Kurama and healed you, Ruby." Robin spoke up and Ruby squeals in surprise when he grabs her hand and placed it on his shoulder. "I'll carry you, Ruby."

"I don't wanna take a-"

"No buts, Rubina." Robin called her full name and flinched to see his stern look. "Do what I say and I'm sure Xi Men would pop out anytime since one of your keys glowed."

Ruby froze and looks down to see Xi Men's key is glowing. She could hear his thoughts and gulping in fear to follow Robin or he would come out to look after her. "Ahaha..." Laughing nervously and jumps on Robin's back. "This is embarrassing..." She muttered under her breath and covering her face on Robin's back.

The others looked amused to see her shyness and Robin's overprotective boyfriend mode despite their under circumstances. They know Robin is always been possessive and didn't want to share his precious gem.

Everyone are changing their heroes costume and Kurama is healing his Mistress and Miss Martian to keep themselves ready for the next encounter to Parasite. Superboy wouldn't allow Kurama to heal him cause he's in good condition especially examining the clone to ensure if he's telling the truth or not. Superboy being a stubborn person didn't allow the nine-tailed fox spirit to check him out. Robin showed them a USB in his hand. "It's not a complete debacle. I picked Parasite's pocket. I got this flash drive." Inserting the flash drive through his hologram computer and accessing the files. "Looks like Parasite's working for Intergang. Everything he stolen. They're all pieces of something! They're putting together a weapon that generates... black holes?" He exclaimed with a disbelief look on his face.

"Oh, come on!" Red Arrow snapped angrily. "To build that, you need a particle accelerator."

"Like the Large Boson Collider in Geneva?" Robin asked the red male archer.

"The circus's next stop..." Celestial muttered with a grim look on her face.

"But now that Parasite can fly, he's got a big head start on us!" Red Arrow pointed out and Celestial frowned.

"I'm sorry..." Miss Martian apologizes and feels bad for lowering her guard.

"It's not your fault, Miss Martian." Celestial assured her and stares down on her lap. "I can summon Sora to chase him out but we're going to be a disadvantage here."

"You're right." Robin nodded his head. "But this thing could wipe out entire cities. We need to hurry. You can still call him and bring Sora back to the spirit world." He suggested and Celestial nodded her head.

"You and I need to hurry." Red Arrow spoke up and glared at Celestial. "There's no point of you calling your spirits, Celestial. Parasite would absorb your spirit's abilities and he's going to be stronger than before. Without powers, the others would hold us back."

"Excuse me?" Celestial stands up and Kurama hissed in anger towards Red Arrow. "I may have magic back but I know how to fight with or without it." She defended herself. "I'm not a helpless little girl, Red Arrow. Kurama healed me and bringing my magic back."

Artemis glared at Red Arrow. "She's right. You're not the only one with a backup bow." She showed them her crossbow. "I just realized something how come Parasite didn't absorb your celestial powers?"

"He's not a Celestial wizard like me." Celestial spoke up and stroking Kurama's head. "Even if he did, Parasite can't use my abilities because he needs to form a contract before calling them."

"To do that you need to break their contract which is unlikely it would happen." Robin commented and Celestial nodded her head.

Superboy slams his hand on the wall to create a huge dent. Everyone are surprised to see his strengths are back to normal. "My powers are back!" He declared and prove everyone at this point by denting the wall.

"How? Even if Kurama healed my sickness, I'm still..." Miss Martian was cut off by the clone.

"I guess Kryptonians recover faster than humans or Martians." He explained and Kurama didn't believe him even one bit.

Miss Martian narrowed her eyes before looking at Robin. "Don't even think about me leaving me behind." She told everyone and Celestial smiles.

"We're in this together and we can stop Parasite." Celestial smiles and Kurama nodded his head. "We know that Parasite absorb our powers right?"

"What are you thinking in that pretty head of yours, Ru?" Artemis asked her curiously.

"He has powerful abilities mixing mine, Superboy and Miss Martian's powers." Celestial pointed out. "Parasite doesn't know we have our weakness as well. For instance, Miss Martian's fire, using my crystal would decrease his life and Superboy's kryptonite."

"You're a genius, Celestial!" Miss Martian gushed and hugging the poor scarlet-haired girl. "I love you so much!"

"Hey, she's mine!" Robin protests and pulling Celestial away from the Martian girl. "She's off-limits."

"Wha- Robin!" Celestial's face is red by embarrassment and everyone chuckled.

Geneva || December 24, 00:37 CET||

Robin kneels down and checks on the unconscious bodyguard. "Trail of destruction, this way." He informed them and they begin to follow the boy wonder.

They all get inside of the facility quietly and Robin uses his small camera to look closer. They're seeing Parasite is doing something on the computer. "Need to take him down." Robin informed them in a hushed tone. "Or at least lure him away so we can safely disengage the-" Superboy cried out in anger and rushed off. "No, wait!"

"He's going to get himself killed!" Celestial exclaimed with a shocked look on her face.

The scarlet-haired girl silently cringed to see Superboy is easily get hurt by Parasite when he uses telekineses against him. "What's wrong with-" Red Arrow swears and readied his weapon to help Superboy out.

"No, wait!" Miss Martian prevents the red archer to intervene.

"Superboy..." Celestial whispered when Parasite absorbs Superboy's powers again.

Parasite is looking at his surroundings. "Alright, Dangers, come on out! Only a couple of minutes before this baby's done warming up... and eats Geneva."

"What do you think?" Miss Martian asked them.

"Big risk to take on a theory." Red Arrow pointed out.

"Celestial, Oichi can copy any abilities without absorbing energy right?" Robin asked Celestial and she nodded her head quietly. "We need her and do you think Parasite could-"

"No, kid." Oichi showed up behind Celestial. "If someone shares the same ability as me. Except the difference is that- he can take their energy away. I'm immune to it and pointless for him to absorb it." She explained and smirked to see his mischief look. "What's your plan?"

Robin told Oichi about the plan and she immediately agreed. Miss Martian showed up with a confident look on her face. "What do you have against Geneva, anyway?" She asked the Parasite.

"Never liked the food, but the menu keeps improving." Parasite answered and rubbing his hands.

"I'm just the appetizer, remember?" Parasite grabs her using telekinesis and she dodges it to kick under his feet. "Here's the main course!"

Red Arrow shoots an arrow towards Parasite as he covered in foam. "Foam?" He asked the red archer. "You think foam can hold me?" His eyes glowed scarlet and start shooting at him by crystals. "Or stop me from killing you by the crystals with a thought? Combined Martian, little scarlet brat and Kyrptonian powers here!" He breaks the foams.

"But do any of those powers free you before I sabotage your death thingy?" Robin asked Parasite with a smirk on his face.

"This one does." Parasite's eyes glowed red and about to use heat vision.

"Not on our watch!" He looked up to see Oichi and Celestial in her star dress Chinese dragon spirit.

"O Wispmasu! (Will-o-wisp!)" Both Celestial and Oichi are combining their attack together and have him surrounded by flames.

Artemis save Red Arrow from falling and nodded her head silently. Parasite stands up. "So clever." He compliments the young heroes. "Trick me into igniting flames... but you forgot... Doofus has a double dose of invulnerability. Fire can't touch me." He started to feel weak all of a sudden.

"That's when you're wrong." Oichi spoke up with a smirk on her face. "Care for an explanation, sweetheart?" Nodding her head up towards Miss Martian's direction.

"Thank you, Oichi." Miss Martian smiles at the Chinese snake spirit. "Unless you make a meal on my powers and get my weaknesses as a side dish!"

"Same thing as my crystals." Celestial pipes in. "The more you used it, your life decrease because only crystal users like me can use it without their life decrease." She explained the half-truth of crystal history.

Parasite is groaning in pain and slumped down on the ground. "Aw, poor baby... something you ate?" Miss Martian asked sarcastically.

Robin approached the computer and deactivate the machine successfully. Sighing in relief and turned around to see Faraday and some Agents are showed up.

"We can take it from here." Faraday informed them and use a fire extinguisher to put out the fire. He kneels down and puts a collar on Parasite's neck. "Thanks for a tip by the way." Thanking the boy wonder. "Definitely helps to prep the inhibitor collar in advance."

"Glad to be of service!" Robin answered.

Celestial silently thanked Oichi to help them before she goes back to the spirit world. Robin finally cleared Haly's name for catching the real suspect.

"Eh? You wanted me to join and speak with Haly?" Ruby asked his boyfriend and blinking her emerald eyes.

"Pretty please, Rubes." He pleads and clasping his hands together. "I need you."

"Yo-you do-don't need me at all." She stuttered nervously and twiddling her thumbs nervously. "You know how I'm socially awkward about this."

"Haly is not a bad person." He assured her and she pouts. "Where's the confidence when you take missions?"

"It's different between mission and personal, Robin." She whines and shook her head. "Please don't force me."

"What if I tell you Haly is important to me." He blurted out truthfully and Ruby blinks. "Please, my beautiful young maiden gem?"

Ruby sighs in defeat and her shoulders slumped down. "I hate it when you pull that card on me, Robin." She whimpered and pouts.

"I'll take it as a yes." Robin gives her a quick kiss and she jumps in surprise. "Hehe~ that's one of the things I love about you, Ruby."

"I hate you too." Ruby sighs again and holds his hand. "Let's get this over with."

"Nah, you didn't hate me cause you couldn't resist me." Ruby raises her right eyebrow at him and dares to challenge his girlfriend. "Did I mention you look gorgeous today, my sweetheart?"

Ruby simply ignores him and knocks Haly's door. "Sir, may we come in?"

"Come in!" They heard Haly's voice and the couples get in. "So... the show will go on." He heard the news for catching the real suspect. "And I have the feeling, I have you, Dangers, to thank."

"Don't know what you mean." Robin answered and Ruby nodded her head.

Haly chuckled. "No, of course not... but I'm guessing you guys will be leaving now." He knows they wouldn't stay in the circus for long and time for them to move away.

"Time to move on." They shook hands and Ruby followed the gesture as well.

Haly stared at the boy. "Well, Dick, I'll miss you."

Robin looks startled. "It's Dan! Dan Danger!" He corrected him.

"Ye-yeah, he's right." Ruby spoke up and Haly didn't believe them.

Haly placed his hands on Robin's shoulder. "Son, you've grown. But some things never change. Like the sight of a Grayson on the trapeze. You can't fake that. Can't hide it."

"No point on hiding, Dick." Ruby spoke softly with a caring look on her face.

Haly chuckled and nodded his head. "Davina right?" He asked the girl.

Robin gives Ruby an encouraging look to reveal her true identity. "Um..." Ruby removes the mask to reveal her face. "Ru-Rubina Hart. You can call me Ruby."

"She happened to be my girlfriend." Robin explained with a proud look on his face and achievement to see Ruby's red face.

"Ah, young love." Haly smiled to see his boy is finally growing up. "Look after Dick for me cause he can cause some trouble."

"Hey!" He glared at the ringmaster playfully.

"He's the one who's looking after me, Haly." Ruby answered truthfully. "He's the best boyfriend I can ever ask for."

"Exact-"

"He wanted me to learn how to butcher words." She answered bluntly.

"That wasn't nice, my gem." Robin gives her a disapproving look and she smiled cheekily.

Haly chuckled at their banter. "Can you guys give an old ringmaster one last favor?" He asked them.

They smile and accept his last final wish.
