I might not wish as much on an actual, human person, but for the sake of story and fiction, I'd be extremely interested and excited if there WERE muscle applied. I want Faye out, Jeph's writing should clearly suggest we're leading to a break between Corpse Witch and Bubbles, which, given that Bubbles is still lead-repairsperson in the situation (assumed because she was helping to train Faye in the ways of facial myomer), and we know that Faye's bonded with Bubbles. It's unclear what feelings she's developed towards Corpse Witch, but it's undoubtedly less of a connection than what we've seen her have with Bubbles.
I think it comes down to who leaves first.
If Bubbles leaves first, it seems likely CW's reaction would be 'whatever, we've got your protogee.'
If Faye tries to leave first, that's where muscle seems likely to come in, given that Bubbles is straight-up military-grade AI.
I think the best, most-interesting course of action would be for Bubbles to leave, but Faye, in her relatively-recent introduction to this scene, stays. That creates tension between Faye and Bubbles. Later, Faye also begins to feel fed up with Corpse Witch's shit, and to TRY to leave, only for CW to try and intimidate her into staying. Faye has connections though. She would contact her old(ish) friend, and request aid, leading to a robot fight, leaving Corpse Witch in pieces and the Faye-Bubbles bromance in full control.
