I'm glad to see Grissom back. Anyone notice how hungry he seemed to see Sara? Like his was just freakin' happy she was there. Of course, it was all in a very "Grissomy" way. I've been thinking about the letter he was writing last week, and I think that when he was writing "I'll miss you" he was referencing the conversation he had with her before he left. Remember that all he said was that? In context with what else he was writing I think he was trying to open up to her, and then at the last minute he decided not to send it.
It was a good, but sad episode. I felt really bad for Keppler, but then I thought you know, that's why you just don't take justice into your own hands. You just don't. I still am super sad he died, but I kind of figured that was the only way it could go down. Poor guy, to find out that your girlfriends father was the one who raped and killer her (or caused her to commit suicide - I wasn't too clear on that one). And then you killed an innocent(ish) man. Sad.
