I haven't watched any of the episodes with Bishop in it yet, but what I hear isn't giving me the warm fuzzies. I had felt, by the end, that Ziva was overused, but I MISS HER! I've watched about 8 episodes of the current season and it's not the same without her. That being said, I would almost rather they didn't replace her at all. Tony and TIm are fine on their own.
