Leo, Raph, Donnie, Mikey, April and Casey all rushed inside the lair each of them halting to catch their breaths as they all panted. Casey flopped himself on the floor the sound of his body thumping loudly while Raph sat down on the stair couch groaning a little as he had his hand covering his chest. Leo noticed a few cuts on Donnie, Mikey and April. Donnie ran inside his lab like he wasn't feeling any pain from the giant gash on his leg and came back out moments later with the first aid kit in his one hand while he held a towel in his other hand. Leo felt a little pain on him as he looked at his shoulder seeing blood leaking out of it sliding down his arm as it dripped off his finger tips dripping on the floor. His cut was really deep.
"Here let me see that Leo." Donnie said walking over to him first. He went to gently pad the towel on Leo's shoulder but the leader pulled away.
"I'm fine Donnie, take care of the guys first it's just a scratch." Leo said trying to fight back the pain.
"Alright, if you're sure." Donnie replied. He went over to Raph trying to check his chest by removing his hand from covering it but his brother whacked him away.
"Don't touch me!" Raph snapped.
"Let me check your wound!" Donnie said firmly.
"Get off!" Raph yelled. The two brothers began whacking at each other until they both got into a sissy fight with each other while Raph kept his one hand on his chest still.
"Guys stop messing around! And Raph, just let Donnie check your wound." Leo said firmly breaking up their fight. Raph grunted in complainant as he pouted his shell against the back of his seat while Donnie slowly removed his brother's hand to whipe off the blood. When Donnie revealed Raph's cut, Leo's heart felt like it shot up in his head as blood was welling out of Raph's chest leaking down past his stomach staining on his belt that held his two sais and wrapped around his waist. Oh no this is really bad, Karai must've gotten him deeper than I thought Leo thought his heart racing. Raph was looking over at Donnie his eyes widened a little as though he were freaked out himself until he suddenly began groaning very loudly while he fell from his seat landing on his side his blood still leaking out of him.
"He's got a really bad wound, I have to take care of him in my lab." Donnie said helping Raph up.
"W-what are you talking about? How deep is it?" Leo questioned his voice breaking from shock.
"Raph has a nasty wound, and it looks like he was stabbed deeper than he looks." Donnie answered. He helped Raph into his lab while Leo and Mikey followed him inside.
"Is he going to d-die?" Mikey asked fear in his tone. Donnie helped Raph on his lab table and turned to Mikey some of Raph's blood on the side of the front of his shell from helping him.
"Well I just need to figure out how to stop the bleeding." Donnie said.
"But will he survive?" Leo asked looking at Raph who was laying on his shell. Donnie turned around to his other lab table sighing.
"I'm not sure, but I'll try my best Leo." Donnie said. Leo couldn't stand seeing Raph in this shape any longer, he turned around calling for Mikey to come with him and both the two brothers headed out of Donnie's lab while April and Casey were still in the TV area both of them standing up as soon as they saw Leo and Mikey walking out.
"So how's Raph? Is he okay?" Casey asked. Leo couldn't speak. He was too worried about Raph that he almost didn't hear what his human friend asked him. Mikey was quiet for a few seconds his sky blue eyes dull from drowsiness yet hollow from fear of his brother dying of his wounds in Donnie's lab.
"Donnie said he'll do everything he can to help Raph, but I'm still worried." Mikey answered.

A few hours have passed since the turtles including their human friends got back to the lair and Leo lied on his shell awake lying on the stair couch waiting for Donnie to report to him  so that he'd know if Raph was going to be okay or not. Leo's heart felt like it was going to break in half at the thought of waking up in the morning tomorrow only to see sadness on Donnie's face and dry tears on his cheeks from the grief of losing his brother. Raph's going to be fine, he's a strong turtle he'll live Leo told himself. He tossed and turned in his sleeping area for quite some time until he finally fell asleep letting himself doze off into a dream. Leo woke up the next morning surprisingly able to remember everything that happened last night as he pushed himself off the couch and headed towards Donnie's lab almost close to the doors until they slid open Donnie on the other side of the opening doors his amber brown eyes narrowed as he looked at Leo.
"How'd it go? Did you stop the bleeding?" Leo asked trying hard not to sound too worried into making his brother nervous.
"Yes the bleeding stopped after a while." Donnie answered. "But there's one problem." he said.
"What's the problem?" Leo asked feeling panicked. Why was Donnie being so secretive all of a sudden?
"It's hard to say." Donnie said. "Raph nearly died last night twice but fortunately he held on and I managed to help him, he'll be okay but he lost a lot of blood." he said to him. Leo felt worry wash over him as he looked over Donnie's shoulder seeing Raph sleeping on the lab bed lying on his side. He does look pretty weak, oh gosh I hope he'll make it longer Leo thought. He turned around walking away and headed to his room. It was nearly 7:00 and he had to get some sleep. Especially since he was up almost all night. Leo lied down in his bed rage suddenly flaring through him as he remembered the fight between Raph and Karai while he began blaming her for dragging them into this mess. Karai had broken Leo's heart for betraying him. He wanted to get back at her. He wanted to hurt and make her beg for mercy in fear. He wanted to get revenge on her, and nothing will stand in Leo's way no matter what. It's her fault Raph got badly injured and she wasn't going to get away with this! Leo wanted to hurt Karai the exact same way she's hurt both him and Raph. She deserves to suffer. Karai won't get away with this! Leo vowed.

(Dang this one took a while because I had a really busy day today so yeah, here it is folks I apologise for the wait. Don't worry the story still isn't over yet I'm wanting to make more so I hope you enjoyed this. And please go ahead and comment any suggestions of what will happen in the next chapter. Should Leo get his revenge? Or should he get over it? Go ahead and help me decide.😀)
