Maybe, but I am getting the feeling that Yael is the one that everybody is regarding as the "low status flunky who gets to be the TF equivalent of a 'Redshirt'", with the majority of the other characters thinking nothing of piling on the abuse. Sort of like, everybody just dumps crap on Yael without consciously being malicious about it, simply because it's apparently the thing to do.
Yael's lazy and has an attitude pre-transformation, and the others do enjoy messing with her post transformation, primarily Lynn and Dina. They're a little bit bitchy for doing that, but they're mostly just having fun about it. It's teasing but not really bullying, and that should be clear when the first beta is out.
This scene isn't in the game btw, it's just a funny promo pic DK did.
