So are you down a Force card, or does she take one of your partner's? If the latter, what if he's already used all of his? (Of course, that's working on the assumption that each player still has their own pool of Force cards. It's entirely possible that in team play, each side uses a shared pool of Force cards, which would make the whole question moot I suppose.)
I have a suspicion that the design team saw that interaction and the multiplayer rules will cover it. I guess we'll have to wait and see how it works out.
