One Jem Too Many is the 4th episode of the 2nd season, and the 30th overall episode, of Jem.
The episode starts with Jerrica cleaning up after the Starlight Girls. After breaking up a fight, Jem remembers she has to do taxes for Starlight Music. Kimber complains about her sister being overworked. Jerrica later declines a date with Rio to do more work, however Jem decides to go out for lunch with him instead. The two go to the Red Rocket Diner, where Jem proceeds to be incredibly rude to everyone. After she insults Rio the two break-up.
The Holograms confront Jerrica about Jem's behavior and believe she's had s breakdown. Jerrica, however, doesn't understand what they mean as she's been busy at work all day. They decide to take Jerrica out to relax, but once again Jem causes havoc while Jerrica insists that it wasn't her. Cool Trash magazine unfortunately has already released a best-selling issue about Jem's meltdown. After seeing "Jem" on TV, the Holograms suspect the Misfits of sabotaging them. They're right—Clash had been pretending to be Jem the entire time. Jerrica refuses to call the police and instead decides to try and fix everything on her own.
Jerrica's scheme is to throw a huge concert, thus baiting her imposter to appear. Danse appears to rehearse dancing for the concert. Clash in disguise as Jem appears at the rehearsal, but Rio notices her and proceeds to get the others to chase her. They end up on a ferry but it's a trap by Eric designed to keep Jem away from the concert while Clash can ruin it. Jem and her friends end up building a raft and getting back to land. They get a hitch back to the concert hall, where Clash gets exposed when she can't sing.
This episode contains examples of:
- Crossover: Hector from The Transformers and G.I. Joe: A Real American Hero appears as a cameo, implying that the series take place in one universe.
- Delayed Reaction: Rio has such a reaction to seeing two Jem's.
- Escapism: The music video to "Imagine Me" enforces the idea that 'Jem' is an escapist character for Jerrica. It depicts Jerrica overworked and Jem relaxing.
- Gosh Darn It to Heck!: Clash-as-Jem outright says "Like fudge we are".
- Hollywood Tone-Deaf: Clash gets revealed because she can't sing.
- No Celebrities Were Harmed: Several celebrities appear under different names.
- Mistaken For Crazy: The first half of the episode revolves around everyone thinking that Jerrica has had a stress-related breakdown. It's really someone disguised as her.
- New Powers as the Plot Demands: Jetta can apparently play the keytar.
- Produce Pelting: Jem and the Holograms get a ride back to the concert by a tomato farmer. Everyone proceeds to throw tomatoes at Clash after she gets exposed.
- Spot the Imposter: While doing so is simple enough (Clash can't sing for her life) much of the problem revolves around most people not realizing there's an imposter to spot in the first place because of Jem's secret identity. The Holograms immediately know something's up when "Jem" appears on tv when Jerrica's with them but Rio doesn't catch on until he sees another Jem sneaking around backstage when the real thing is rehearsing.
- Voice Changeling: Clash can do a pitch-perfect Jem impression. Not even Jem's siblings realize that it isn't her.
- What Happened to the Mouse?: Ms. Bailey would sure have been useful at the start of the episode. She isn't in the episode, thus allowing more room for Jerrica to be shown as overworked.
- The Workaholic: Having to take care of a house full of children, being the manager of a music company, and being a part-time singer has left Jerrica this way.
- Your Cheating Heart: Done rather blatantly when "Jem" goes on a date with Rio, right after Jerrica declined a date with him. Afterwards Rio goes to complain to his girlfriend, Jerrica, about his other girlfriend, Jem.
