Ink takes out his paint brush, about to make a portal when he notices that Kat ran off and facepalms as he mutters to himself, "Error's gonna kill me...... And probably all of them....." He then begins running after her as he yells, "Come back!!!!!!!"

'Welp I need to find her before Error kills everyone in my absence.' Ink thinks while chasing her.

As Kat's being chased, she runs up to where a river is, where a person wearing a cloak is standing on a boat. She hops on the boat and tells the river person to take them wherever, and then they're off.

"Tra la la. I am the riverwoman. Or am I the riverman...? It doesn't really matter. I love to ride in my boat. Would you care to join me?" The River Person says as they head to Waterfall.

"Dang it..." Ink mumbles as he sees Kat being taken away by the River Person.

MEANWHILE, IN THE ANTI-VOID

"Where are they?" Sans asks, slightly worried, 'I hope they're alright, and didn't run into any trouble......' He thinks.

"No idea.... Shouldn't they have been back by now...???" Faith asks as she looks at Error, automatically assuming that he's the most responsible in this place.

"They should be..." Error responds with a slight frown.

"Then where are they?" Faith asks.

Isa wakes up, still laying on the ground, with a slight groan, really groggy as if she woke up with a hangover. She has a slight headache, and she clutches her forehead until it disappears.

Dream walks over to Isa and offers her a hand to help her up asking, "You okay?"

"Yeah, I'm fine!" Isa grins at him as she takes his hand, and he pulls her up.

Siren begins waking up in Red's lap, she nuzzles him a bit and yawns, her eyes opening a little bit. Red, who's clearly not used to this, blushes a light red, but still irritated from her falling asleep on him in the first place.

"Hey, where is everyone?" Siren asks once she's fully awake.

In Underswap Kat is now exploring Waterfall while Ink is running through Waterfall, trying his hardest to stay hidden, hating his life right now.

"Blueberry fell asleep, so Ink went to return him, and Kat insisted that she go with him..." Faith answers Siren.

Sans begins to worry about Kat even more, 'Where could she be...? Papy better not have hurt her!' He thinks worried and slightly angrily.

"M'kay." Siren responds nodding at Faith.

"That's a bad idea...." Isa says as she stares at Faith.

"She kinda insisted and jumped on his back." Faith replies.

"Again... BAD idea...." Isa grumbles out.

"You wanna go after her don't you?" Error asks looking at Sans, noticing the worried look clearly written across his face.

"Maybe..." Sans mumbles out in response to Error, 'Just don't want her to be hurt...' He thinks semi solemnly.

"Anyone else?" Error asks looking around at the others.

"I would rather stay here." Faith says as she sits on the floor.

"She likes exploring, and can get lost easily...." Isa explains to Sans and Error.

"The less of you that stay here, the better it is for me." Error says.

"I'm staying." Siren responds.

"Damn it." Error grumbles frowning.

"I'm going." Isa says with a slight smirk upon her face.

"I'm staying here too." Red and Dream say in unison.

"Fine, but if any of you start making out, I'm throwing you all in Underfell." Error says looking at Siren and Red with a slight glare.

"ERROR!!!!" Red yells scowling at him, still lightly blushing.

Siren blushes and buries her face into Red's jacket. Error just snickers at them. Red blushes a bit more, still scowling, trying to keep his attention off Siren.

As Error makes a portal to Underswap, Ink reaches the glowing path in Waterfall and sits down, panting out, "Where....... did........ she....... even go......?"

Meanwhile, Kat is hanging out with the Flowies in Flowey Village, she is talking with a Flowey.

"Hoi, I'm Flowey! and this is my fwiend.." They took turns saying, all looking at Kat.

"Hi, I'm Bob." The final one dully states, looking at Kat as well.

"Hoi i'm Ket!" Kat responds with a goofy grin plastered on her face.

"Let's goooooo!!!" Isa says jumping through the portal.

Sans jumps in after her and spots Ink, walking over to him with a slightly angry expression spread across his face, "Where is Kat?"

"I have....... literally no idea......." He says finally catching his breath and he stands up to explain, "I got yelled at by Papyrus, and as I was making a portal back, she ran off. I tried to chase her, but she got on the Riverpersons' boat."

"You lost her!?" Sans yells at him.

"Seriously, you never let her out of your sight." Isa states matter of factly while facepalming.

"She ran off!!!!" Ink argues, "I told her to follow and she ran away!! I've been running all over trying to find her!!"

"She should be back soon." Isa says nonchalantly before apologizing for Kat, "I'm so sorry about her."

Sans begins running towards Flowey Village, which Kat just so happens to be walking out of, smiling happily as she goes. Sans spots her and runs to her immediately, relief washing over him as he hugs her tightly.

"There you are! You had me worried kid." He says putting his hands on her shoulders, keeping her at arms length, staring into her eyes, 'Thank goodness she's alright...' He mentally sighs in relief.

Kat's eyes widen in shock as she stutters out, "I-I um.... I-I'm sorry...." She then looks down at the ground in shame.

Sans takes his right hand off of her shoulder, places it on her cheek, then moves his pointer finger down to her chin and pushes her head up to make her look at him, "It's alright, I'm just glad you're okay sweetheart."

'Damn why is she so cute....?' Sans thinks, trying to keep himself from blushing and calm.

Kat blushes profusely because of his actions, and as Sans leans down a little bit to kiss her on the forehead, she feels butterflies flutter about in her stomach. A slightly darker pink dusting her cheeks.

WITH INK, ERROR, AND ISA

Ink is leaning against Error, thinking he's a wall, "I ran from Snowdin to here trying to find her." Ink explains, while Error death glares the artist for touching him.

"Welp, hi again." Ink says looking up at Error. He then puts his hands behind his head, continuing to use Error as a wall.

He then glances over towards the direction of Flowey Village and he spots Sans and Kat, "Well hey, Sans found her." He says nonchalantly.

"I am not your pillow." Error growls at Ink.

Ink raises an eyebrow at Error, smirking, "You're not doing anything to stop me."

Error just gives up, and doesn't care enough to really push Ink off of him. Ink just closes his eyes, hands still behind his head, relaxing.

Isa beams noticing the two, runs over to Kat, and tackles her into a hug. Sans jumps back to dodge Isa's hug attack.

Kat groans in slight pain from the impact, "ISA, GET OFF OF ME!!!" She yells.

Sans grabs Isa, and easily pulls her off. Kat gets up, brushes herself off and scolds Isa, "Isa, you need to stop doing that. I could break a rib or something. You could be a football player!"

"Sorry!" Isa apologizes, 'Geez..... I was just trying to show you that I actually care about you....... Sorry Kat.....' She thinks, Kat's name thought in a venomous way before saying with a sing song voice, "Sorry! Just can't hold myself back sometimes!~" She then skips off, still feeling down.

Error rests his chin on Ink's head, clearly bored already.

"Getting bored, Error??" Ink asks.

"Shut up." Error says, not really wanting to make conversation for now.

"I guess we should get going......" Kat mutters rubbing the back of her head nervously as she starts walking towards the group, Sans following suit.

"Yeah, hey" Sans starts as he looks at Error and Ink, "Can we go back now?"

"Can we head back meow? Please?" Kat asks purring as she makes the joke, Sans chuckling a little bit.

Ink opens his eyes, "Sure." He responds ducking away from Error without warning.

Error loses balance, and falls on top of Isa, who just so happened to be in that very place in time. Ink begins laughing at Error.

"OOF!" Isa grunts in pain as Error mutters, "Ow..."

"Nice balance, Glitchy!!" Ink says mockingly, continuing to laugh.

Isa continues to groan in pain while on the ground. Error stands up and dusts himself off as he wraps some strings around Ink's mouth in a tape like fashion shutting him up.

"Oi! If you fall on someone, help them up!!!" Kat scolds Error and Ink, even if Ink didn't actually fall on anyone.

"Fine." Error says as he reaches a hand down and helps Isa get back on her feet, glitching at the contact.

"Thanks...." Isa mumbles as she accepts his help.

"That's what ya get for tackling me two times. Karma is a biscuit sometimes ain't it?" Kat asks Isa in a slightly mocking tone making Isa turn and glare daggers at Kat.

Ink's groans and laughter is muffled by the strings, as Sans asks once again, "Can we leave please?"

Ink takes his paintbrush off of his back, twirling it around, messing with it, strings still keeping him shut up. He makes a portal that leads back to the Anti-void with his paintbrush, then he puts it back on his back. Error snickers at Kat and Isa's arguing.

"They're back." Siren says simply as she hears a portal open while sitting in Red's lap.

Sans grabs Kat's hand which causes her to blush, and jumps through the portal. 'H-He aaaaaaaahhhh-' She thinks becoming a blushing mess.

Isa trudges through the portal, glaring at Kat. Ink jumps through the portal after everyone else, and then attempts to pull the strings off of his mouth.

"Oh, welcome back again!!" Faith greets them all as they come back through the portal.

"Yo!" Kat beams, lifting her free hand in a type of wave that doesn't require moving it.

"Welcome back....." Red mumbles still blushing because of Siren.

Ink is still trying to get the strings off of his mouth with no success, Error laughing at him. Ink death glares him with inaudible yelling.

"Welcome back guys!!!" Dream greets them as well with a bright smile.

Ink looks at Dream while pulling on the strings.

Dream tilts his head while looking at Ink, "What happened?"

Ink points at Error and then crosses his arms.

"Oh, I don't think I can help, sorry." Dream responds before walking over to Kat and hugging her.

Kat hugs Dream back and greets him, "Hey Dream!~"

"Have you two been like that the whole time we were gone?" Sans asks turning to look at Red and Siren.

Siren shrugs in response while Red says in a slightly annoyed voice, "Unfortunately..... Yes...."

'Though it's kind of nice to be able to do this with someone....' Red thinks mentally sighing.

"I can leave if you want me to." Siren suggests looking at Red.

"I-I.... I-It's fine...." Red stutters out, and blushes more looking away, 'Goddamnit, why is this happening to me?' He thinks, kind of groaning on the inside.

Ink furrows his eyebrows while muffledly growling at Error. Error is just laughing his head off at Ink which earns him a slap and a harder death glare from Ink.

"Ouch, hey." Error responds as Ink taps his foot on the floor.

"Uuuuuuuuuuuuuuggggggggghhhhhhh, FINE!" Error groans and removes the strings.

"Thank you!!!" Ink says then crosses his arms over his chest, "At least we're even now."

"Don't mention it...... Ever." Error responds.

"Actually, you're not even. Error is taller." Kat tells them.

Error starts laughing even harder than before. Ink growls, grabbing his paintbrush, dashes past Kat, covering her in pain, then snaps which turns the paint into chains, causing her to fall to the ground. He then walks back over to Error and hits him on the head with the paintbrush. Sans also laughing along with Siren snickering. Ink glares at them all, holding up his paintbrush.

"But then again, I'm shorter than Ink..... Oh, okay then. Also, WHY ARE YOU LAUGHING SANS?~" Kat whines while pouting up at Sans.

Sans immediately stops laughing, grabs Kat, and tries to get rid of the chains, he then death glares Ink.

"She started it." Ink mumbles looking at Sans.

"This is pretty fun! I'm being for real kidnapped by Ink!" Kat beams grinning, suddenly happy again.

"Try me bitch." Sans mutters under his breath still looking at Ink then snaps his head down to give Kat a look of confusion, "Really?"

"Yep! I've always wanted to be kidnapped!~" Kat says with a slight sing song tone, still grinning a toothy grin. 

Ink turns and looks at Error and mouths to him, 'Did I kidnap them..?? I still don't remember.'

Error facepalms at Ink.

"Oooookaaaayyy...." Sans drags out, still confused.

"Are you some kind of masochist or something?" Red asks Kat.

"I don't know, am I......?" Kat asks tilting her head slightly, confused.

"Well that's a new one." Error mumbles staring at Kat.

Ink looks around, then takes his paintbrush and paints two couches for people to sit on so no one touches Error's. He then creates a coffee table that is placed in front of both couches. The couches are set up in an L type of shape, both the same size, but they're not touching. He then sighs and snaps his fingers which release Kat from the chains.

Kat smiles at him 'innocently', squealing before realizes she's no longer in chains and isn't being kidnapped, "NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!~" She then sulks, puffing out her bottom lip in a pout.

Ink sits down on one of the couches, putting his hands behind his head to relax.

"You need help kid." Sans comforts her, but is being real about it.

"Ouch...." Kat gets up, dusting herself off slightly before sulking and walking over to the couch that Ink isn't on. She tries to sit as far away from Ink as she possibly can.
