Summary
The turtles had seen plenty of unfortunate, painful mutations over the years. They just never thought they would have one of their own go through the same experience. But when Donnie saves Casey from a mutated fate, the genius is reborn anew as a turtle-alligator hybrid. Controlled by instincts and uncertainty, it will be a long and hard journey to return Donnie back to normal. But as time goes on, is that even a possibility? How much is Donnie willing to sacrifice to fix himself? Thank goodness he has his family and friends (and maybe more than friend Casey Jones) there with him.
A 2012 "bimutated Donnie" au inspired by the "Good Genes" episodes of the 2003 cartoon, with Karai and Splinter being good family members, a friendship between Leatherhead and Donnie similar to the 03 show, and some endgame Jonatello.

Summary
“Your stories of how you got together are things like from fucking fairytales. The literal definition of soulmates, true love, and love at first sight. You took one glance at each other before you guys knew and I’m just wondering,”
Raph paused before whispering. “When will that happen to me?”
Alternatively:
Being locked on a spaceship with nothing but couples surrounding you, makes a guys feel a little lonely. Even after all the fighting and the current search for the black hole generator, Raph's thoughts about finding love plague him. Wondering when will be the day he will find someone for him.Could be read as a stand alone but recommend reading A Different Beginning to get context from their backstories.
