The Glenn getting laid scene felt very out of place... he didn't have much former contact with that chick and then BAM!... sexy time. That would be like me going to class tomorrow, asking the girl I sit next to how her weekend was, and then taking her to the bathroom for a hammertime love making session.
And I agree with Direshadow, the Cherokee Rose was a very cool scene. Daryl just gets more awesome each episode.
Also, it looks like Daryl's brother is coming back next episode, that'll be interesting.
