The Good, The Bad, and Casey Jones

"The Good, The Bad, and Casey Jones" is the thirty-fourth episode of the series. It aired on February 2, 2014.

Plot Synopsis
In a voiceover, Casey Jones courageously vows to eliminate all of the mutant and crime threats in New York City (as he thinks it is his calling and his destiny). Thus, he dons his signature hockey mask, grabs his hockey sticks and baseball bat, and prepares himself for battle...

In the sewers, the Turtles commence in a free-for-all spar with one another on their Master Splinter's orders. Mikey and Donnie are quickly defeated and eliminated, but Leo and Raph are not. The two brothers then face each other. Both Leo and Raph waste no time disarming one another of their weapons, but when Raph pursues his missing weapon, he unkowningly leaves himself vulnerable to one Leo's kick attacks...Raph is greatly dissatisfied with this, however, and he pummels Leo really hard in retaliation, leaving his brother nearly unconsious on the ground. Both his two other brothers and Splinter condemn this rash action, so Raphael decides to leave the lair to both think about what he's done and get a breath of fresh air.

Meanwhile, Casey is surveying "his" city from a rooftop, writing things down in a diary while doing so. He soon hears a nearby fracas, which turns out to be The Purple Dragons coercing a defenseless man into giving his wallet to them. The muggers get their wish, but then Casey shows up and begins to fight with them. Casey proves to be quite a challenge for them, and he is quickly able to subdue all of them in single combat. Unbeknownst to him, however, Raphael is watching from a rooftop. Ironically, Raphael says to himself, "That guy is out of control!!" Seeing how Casey is about to mercilessly take them out, Raph intervenes and grabs Casey's hockey stick away from him. Casey is kind of shocked to see yet another mutant, but this does not intimidate him; The 'street-banging vigilante' once again springs into action. Raph and Casey's brawl unfortunately allows the three reprobates to escape, upon which Casey begins blaming Raph for letting them go. An even more heated fight ensues, but neither seems to be able to mantain the upper hand for long. In the end of the duel, however, Casey manages to electrocute Raph with some type of stunner, and he then escapes by jumping onto the rear end of a passing taxi cab. Raphael also retreats. In the lair, he mutters an apology to Leo for his behavior earlier that night. However, Donnie and Mikey then humorously insult Raph, which once again causes Raph to become angry, and this forces him to leave the lair yet again!

The next day, at Roosevelt High School, April and her newly introduced friend, Irma, walk up to Casey, who is sifting through stuff in his locker. When he turns around to talk with them, it is revealed that bandages are all over his face. They ask what happened, but to no avail - Casey lies that he recieved the injuries at the hockey rink, which both Irma and April have a hard time believing, as they know that the rink was closed ever since the mysterious fight broke out there...Irma then proceeds to her next class, forcing April to come along with her (though Casey is able to reveal to April that he fought with a crazy mutant the other night).

The following night, Casey is on the very same rooftop once again, thinking about Raph and commenting that he is quite a worthy opponent. Coincidentally, he spots Raph kicking stuff around on another rooftop not long after and goes to follow him. Unbeknownst to Casey, however, a squad of Foot-Bots are following him, too!! By following the sound of Raph's yelling, he goes into the sewers and discovers the Turtles' lair...Casey accidentially reveals his presence, and all of the Turtles are soon onto him. The revelations that both Raph and April know Casey suprise the other Turtles. April bluntly inquires what he's doing there, and in turn, Casey asks what she's doing with a bunch of mutants. She grudgingly explains that the Turtles were the 'friends' that she told him about earlier, and then, she introduces all of them. Splinter then appears, and Casey is so stunned that he passes out...He is soon woken up by April, however. After everyone introduces each other, April senses the Foot-Bots' nearby presence with her very acute hearing sense. The Foot-Bots then show themselves and begin invading the lair, much to everyone's shock and dismay...

The team manages to hold their ground pretty well, and they begin to defeat the robots, one by one, though more keep entering. One robot stands alone from the fight, scanning the location of the lair. Fearing that he will inform somebody else of their location, Raph and Casey decide to put their hostility towards eachother behind themselves and go after the robot (who is now running out of the lair) together. During this side-adventure, both Casey and Raph rescue each other (Raph, from getting run over by a train - and Casey from getting thrown off the top of the train by the robot), which further strengthens the two's budding friendship. After numerous attempts to subdue the wild robot, Casey finally manages to electrocute it only seconds before it reaches the streets, and Raphael throws his sai directly into the robot's head, ultimately finishing it off.

The two then head back to the lair and find that the Foot-Bots there have already been reduced to scrap metal as well. The two engage in a miniature celebration due to their victory, showing that they are now best buds, and poor Donnie exclaims that there is now two Raphaels - and the two new best friends then head up to the streets looking for more skulls to bust...
