Spock is I think going to be the one to discover that Winter isn't Winter? He'll share this with anyone he can so that they can devise a way to stop her. (I'm not sure if he'll have access to his device during this so it may or may not have to be in person). But it's still her body so if anyone tries to harm her to end this whole thing he'll step in unless no other solution can be found, in which case, sorry babe.

Also as an fyi he won't even be abducted until the 15th or 16th since I'll be hiatused while I'm on vacation.
