I loved last nights episode, the dialog between Michonne and Merle was wonderful; really got to know Merle more before his death.
I found it interesting how he said he had spent alot of time thinking about Rick, he mentioned the fact that Rick had tried to come back for him. I wonder if he had come to the conclusion that he would have been better off trying to fit in with the Alanta group. Considering he had never killed anyone until he worked for the governer , he musta figured Rick would not have asked that sort of thing in order for him to stay. ( Course , Rick pretty much DID ask that of him...... )
