Thomas Stories: Heroes
Kara shows Stacy and Billy that she's been working on a frame for the picture of Mr. Conductor. The four of them discuss the drawing and how an evil duplicate of Mr. Conductor was created from it after the kids sprinkled some of Mr. Conductor's gold dust on it. Stacy remembered that J.B. King is coming to the station later to pick up the drawing. Kara and Stacy go into the main station where Stacy asks Kara to clean up a mess she made while a frame for the drawing. Though she would not, Kara starts cleaning up.
Schemer proceeds to tease her about the mess. Once Mr. Conductor appears with his whistle out of tune, Kara asks for Mr. Conductor's help in cleaning up her mess. Mr. Conductor states that she should clean it up since it's her own mess. Mr. Conductor then leaves to get his whistle tuned. As Mr. Conductor leaves, Kara grabs some of his gold dust. She sprinkles it on the picture of Mr. Conductor, bringing the Evil Twin back to life. Kara makes the Evil Twin promise to clean the mess she made and then go back into the picture. The twin agrees, and asks Kara to make sure no one is watching. As Kara does so, the Evil Twin plots to have the real Mr. Conductor to become trapped in the picture. Kara comes back and the twin makes the mess magically disappear. Once he's finished, he tells her he'll help her pay back Schemer for teasing her. While Kara distracts Schemer, the Evil Twin creates a giant, man-sized nickel which chases Schemer out of the station.Inside the Jukebox, Tito has noticed the giant nickel. He becomes slightly obsessed and makes it his quest to find and capture it.
Back in the station, there are two boxes of chocolates on Stacy's desk. She had been planning on giving them to J.B. King when he arrives. The Evil Twin proceeds to open one box and smash them. Kara then comes in and tells the Evil Twin it's time for him to go back into the picture, but the twin refuses. When Kara threatens to tell on him, the twin points out that nobody will believe her. Stacy enters the station and is impressed with how clean it now is. She goes to give Kara a piece of chocolate for doing such a good job, but discovers the smashed chocolates in the first box. Upon opening the other box, Stacy and Kara find not chocolate, but creamed spinach. Stacy tells Kara to take the boxes back to Barton Winslow's General Store and ask for two new ones. Kara tries to tell Stacy about the Evil Twin, but Stacy is too busy trying to make sure everything looks nice for when J.B. King comes. The twin then gets Stacy out of the station by impersonating Mr. King over the phone telling her and Billy to come to Leaky Park as soon as possible.
Schemer soon returns to the station, covered from head to foot in a suit of armor. Calling himself Sir Scheme-a-lot, he challenges the “monster” nickel to show itself. The Evil Twin orders the Jukebox Puppet Band to play a sad song called "Danny Boy". They do so, which makes Schemer cry, causing his armor to rust to the point that he can barely move. The Evil Twin then knocks Schemer unconscious with a nickel. Kara soon returns with two new boxes of chocolate. Mr. Conductor appears and still hasn't gotten his whistle tuned. Kara explains what happened, without letting on that she is talking about herself freeing the Evil Twin.
Kara tells Mr. Conductor the truth and apologizes for what she’s done. The two ponder where the Evil Twin could be. Just then, a whistle blows and they see him heading towards them driving the model engine. He has commandeered the model engine and crashes it into arcade steps. Mr. Conductor and his Evil Twin are now standing side by side. Kara can’t tell which is which until she remembers that the real Mr. Conductor's whistle is still broken, and asks both to blow their whistles. She identifies the Evil Twin and pours a pot of glue over him, in the hopes he will disappear. It works and the Evil Twin returns to being a picture.
Just then, J.B. King, Stacy, and Billy enter the station. Mr. King has no idea what Stacy is talking about when she mentions the phone call about Leaky Park. Schemer wakes up and asks if Mr. King is there to help him catch the monster nickel. Mr. King becomes a bit concerned about Schemer. When Stacy says "boy, what a costume!," the word boy makes Schemer think of “Danny Boy,” the song that made him cry earlier. He quickly runs home to change out of his suit. Dealing with Schemer’s behavior makes Mr. King say that he sometimes considers closing the station. Kara, Stacy, and Billy quickly persuade him not to, saying that Schemer is simply a bit paranoid, but he means well. Kara gives Mr. King the picture of Mr. Conductor, which he is very happy to have. J.B. King thanks Kara and leaves the station, debating where he should put the picture.
A little while later, Stacy, Billy, Kara, and Mr. Conductor are in the workshop. Mr. Conductor has finally had his whistle fixed. Billy is working on repairing the model engine. Kara apologizes once more for what she did. Stacy tells Kara that everyone makes mistakes, but that we become better people by learning from our mistakes. Kara says she's learned that Mr. Conductor's Evil Twin is trouble. Mr. C agrees, saying that the twin is "double" trouble.
This episode provides examples of:
- Big "NO!": The evil twin as the glue pot is being dumped on him.
- Deus ex Machina: They're able to tell the two twins apart because the real Mr. Conductor needed to get his whistle tuned. Yes, it was stated earlier in the episode, but what a convenience that he never got it tuned despite his intentions to do so.
- I Have This Friend: Kara tells Mr. Conductor that she has a friend who asked someone she shouldn't have to do something for her when she should have done it herself, resulting in that person making a mess of things. Mr. Conductor tells Kara that her friend's situation was similar to Bill and Ben's when they let the Troublesome Trucks take charge of things. After telling her the story, Kara confesses to Mr. Conductor that her friend was her and that she let Mr. Conductor's Evil Twin out of his picture to help her clean up the station, only for him to make a bigger mess.
- Indy Escape: Schemer as he tries to run away from the "monster nickel".
- Pun: Mr. Conductor states that he'll consult Ms. Early Bird to get his whistle tuned. Not only because she's the best whistle tuner in the business, but because she's "cheep".
- Sequel Episode: To Double Trouble.
- Spot the Imposter: When Kara has to distinguish Mr. Conductor and his evil twin, she remembers that the real Mr. C's whistle was out of tune, and asks both to play a note.
