Season 2
THE GOOD, THE BAD, AND CASEY JONES

Raphael is out at night, trying to cool off when he sees Casey fighting some Purple Dragons. He thinks that he's out of control and decides to step in. He lightly attacks Casey, before sneaking back into the shadows. Casey pulls out a bat and demands to know whose there, and Raph steps out into the light. Casey is surprised to see another mutant and Raph asks if he has a problem with that. Casey asks if he's meant to be some kinds of turtle ninja and laughs. The Purple Dragons start to run off, and Raph tells Casey to let him handle it. Raph then says anger is a dangerous ally and pushes Casey, telling him to cool off for a while. Casey decides he's done with Raph and the two start to fight.

Raph ends up knocking Casey into the trash, but he quickly bounces back. He's angry that Raph caused the Dragons to get away, and decides that he'll pay. They fight some more, and Casey can't help but compliment Raph's throwing stars. Raph decides to show him his sai, and they continue fighting. Casey knocks Raph to the ground and asks if Turtles are supposed to be endangered. Raph says only the one's who can't fight and proceeds to kick Casey in the face. They take their fight to the street where Raph gets the upper hand, and seems to be about to stab Casey, till he stops himself. He questions what he's doing and thinks that he might have anger issues, when Casey tazes him. Raph gets away, and Casey hops on the back of a cab, yelling that Raph hasn't seen the last of him. Raph yells at him that he better run, but runs low on insults.

Casey it out at night drawing, still in pain from his last fight with Raph, when he sees him over on a rooftop. He follows him and watches him go down a manhole cover, quietly slipping behind him. He finds the layer, and is surprised to see that there's four turtles. He ends up accidentally getting their attention and Raph can't believe it's him again. Mikey and Donnie restrain Casey, Mikey asking if Raph knows him. April then comes out of talking with Splinter and intervenes, introducing Casey to all the turtles.

The foot robots then enter the lair, and Leo says that Raph led them there. Raph immediately blames Casey, much to Casey's annoyance. He says they followed Raph as well, and they argue some more till one of the robots starts to leave with their location. Casey says he's on it, but Raph pushes him out of the way and says he doesn't need his help.
