I still wonder if Renard is thinking Nick is an old-style 'kill'em all' Grimm, and is protecting him 'cause he thinks that Nick can be turned loose on his families when the time comes. If he thinks that, Renard may be of the evil variety. If he knows Nick isn't killing randomly like other Grimms did, then he may be a good guy. It's one of the better 'is he good or bad' stories I've seen. But I hope they don't drag this thing with the cab-stealing killer out too long.
I like everything about Monroe and Rosalee. Still want the spin-off. And the cat thing was awesome; I laughed heartily.
Trivia note: the guy who wrote the episode is the same guy who was supposed to have replaced Greenwalt as co-exec producer on
Angel. It's the circle of life in Hollywood.
