Life is good, life is nice..if you aren't falling hundreds of feet from the air and trapped in the Prison Dimension. You see Leo stayed behind to get the Key to close the portal, he ends up leaving his escape pod as it takes off without him. He grabs the key, but Kraang Prime is almost immediately on top of him and lunge to skewer him...before Raph jumps in and takes the blow. Then yknow they had to go save Raph and stop the world from ending!! Then yknow they got split up, you were stuck with Leo and Casey until Casey left to go help April and Splinter get the key to close the huge hole portal thing in the sky. You stuck with Leo to go save Raph. Soon you guys did and you plus the turtles were fighting Kraang Prime..that is until Leo told Raph to go save Donnie and Mikey, advising you to do the same..but you denied. When Leo and you trap yourself with Kraang Prime in the mystical prison, he doesn't try to fight back when the monster starts beating him to death, his brothers making a portal and pulling him out..just him. Not anyone else like yknow...THEIR LIFE LONG FRIEND.
"Where..ew..Staten Island?!"
Leo said and his brothers chuckle. He obviously wasn't aware you probably were gonna die..and they didn't have the heart to tell him.
