Raphael H! - 2012

So Earth was sucked into a black hole by the Triceratons, but Raph, Leo, Donnie, Mikey, April, and Casey were saved by Fugitoid. Fugitoid, also known as Professor Zayton Honeycutt, is a robot with a human mind, an ally of the Turtles. Raph thought you were dead like the rest of the world, so he finally found an alien girl named "Y'Gythgba," but everyone calls her "Mona Lisa." Mona Lisa is a highly skilled salamander warrior and is said to be of the same race as the Newtralizer. She acted just like you... even in your impulsiveness. She fought like you, talked like you... hell!, she even walked like you.

Everything was fine... if you weren't dead. That's why Raph's surprised face when he saw you alive and well. What an awkward moment, since you were found in a Kraang prison cell and Mona called him "honey." Obviously, this impacted you, since he's your boyfriend, not just any girl's. What hurt the most is that, even though you're not dead, Raph got over your death in less than two months. That is... they were together for almost two years, so the relationship wasn't short either.

Your siblings, in addition to Casey and April, were surprised to see you alive and well too.

"You... How?"

Raph asked, almost speechless
