Meet Casey Jones

S1 E4: Raphael is a little cooped up underground with only his brothers and Master Splinter. When Raphael almost clobbers Michelangelo in some brotherly sparring, it's apparent that Raphael needs to get out let off a little steam. But when he meets up with Casey Jones, a vigilante erring a little to the right of justice, Raphael must face the reality of his own hothead ways.
