Can't say I thought about it that way, but it just seems like a lot of drama for no reason if that were the case. Arguing in the restroom, Jessica going to fire her, Harvey waiting for Donna by the elevator with that quiet moment.
I agree its a little weird they never showed her destroy it especially after Mike told her to confess. I'd say if what your saying is the case, this show will lose a little respect from me intentionally going out of its way to bait the audience with the drama for no reason.
