Doubt Mika will fully pin it on him, well she may pin it on him but then make sure the whole thing isn't a big deal. While she likes f'ing with him she doesn't actually want to ruin his life.
The author could actually redeem her character by her remembering back to how much her accusing him of stalking hurt him and then show some growth in her actually not wanting to accuse him of it again.
Will this happen? Fuckin' nope. She never learns anything and is an abusive prick.
