Leo and Donnie were fighting. Donnie then hit Leo in the face and Raph had to pull him away Raph: "Would you two stop it already? Brothers don't treat each other like this!" Donnie: "That's the thing! We AREN'T brothers!" He snaps as he pulls himself out of Raph's grip Raph: "Donnie!" Donnie: "It's true! None of us are related!" Mikey: "We... aren't brothers?" Donnie the explains how each of them is a different species of turtle and they each had their own set of parents You walk in and look confused since Mikey, Raph and Leo are on the verge of crying (ESPECIALLY Mikey!) and while Donnie is still angry... he also has a few tears in his eyes...
