Sorry to haul this back out to dust it off.

But there WERE, originally, only 4 in Jem & the Holograms. I've been watching the episodes on the Hub. They auditioned a drummer because Shana (the original drummer) wanted design clothes and that new member is Raya. She just didn't come in until the first episode of season 2. (looked that up on IMDb during the episode) Same episode that The Misfits got their 4th member, Jetta.

So, technically, we're both right. And I have thought entirely too much about this. LOL
