Donnie heard a roar and jumped hard, he stepped back.

"Mikey..?" Donnie was both terrified and disgusted.

'Mikey' roared at Donnie again and Donnie covered his face with his arm. Donnie wanted to run so bad, but his only way out was the open door that Mikey stood in front of, he needed to get passed Mikey and avoid the mutagen covered floor.

He ran for it, using all his tricks and tactics to dodge the mutagen, he didn't look back. The door led straight to the outside and Donnie had to find the nearest manhole before he was seen.

He ran and ran through the dark underground, he stopped and vomited out his fear, feeling regret; for leaving his brothers as they were, and dizzy, so dizzy.

...

Donnie woke up, when did he sleep? he didn't really know where he was but he felt safe. He sat up and his head swam in all directions, he wanted to lay back down but the homey sounds from the other room were calling him. he swung his legs over the bed and lazily walked to the sounds he heard. He saw his brothers all whispering their words, Master Splinter looking over them with grief.

"...We can't just leave him lying their..." Leo said, he wasn't the same Leo he was broken.

"I wish we could do more...I wish we could save him." Mikey broke down, Raph compforted him.

Didn't they see him standing there? Why was Mikey crying? Who were they trying to save? So many questions.

"Guys is everything alright?" Donnie asked, he really wanted to ask how they were alive right now.

"Sooo... should we bury him?" Raph asked.

"Raphael," Master Splinter scolded.

"Seriously, Leo said we can't leave him lying there."

"Yea, I didn't mean bury him! What if someone digs him up?" Leo backed himself up.

"Donnie just died and you guys don't even care, you just wanna get rid of his body!" Mikey sobbed out, silence rang around the room. "W- well not me, I care and I'm gonna do something about it." Mikey stormed away.

Donnie stood there shocked, he's dead? He wanted to cry but the feelings and tears wouldn't come. He felt alive. Donnie's theory was if your dead, you have unfinished business, in Donnie's case he didn't really have any business he needed to finish.

Donnie walked around the lair, nobody really said anything after Mikey stormed away and he wanted to see if he was okay, even if he couldn't compfort him.

Mikey just ate his problems away and wasn't doing anything about anything at all. Donnie rolled his eyes and walked away. Time was passing and he didn't get tired, he just watched everyone go to their rooms and sleep. During the night Donnie saw Master Splinter looking in Donnie's lab. Donnie looked down, he must be so hurt. Master Splinter closed Donnie's lab door and went to go back to sleep, he hated watching everyone grieving.
