The way the speculation train is going, it might become an Untwist if Marrow is actually the traitor. As for Vine, I think he's just a super serious, somewhat odd guy like Ren. He doesn't scream traitor.

Also, it would be super disturbing if Elm were the traitor. She'd be something like Rekka Hoshimiya from Fire Force, and that guy was unnerving because he maintained his peppy personality even as he sacrificed a bunch of kids for the Pilot Flame and attempted to get rid of Tamaki.
