Seems like Rick and Morgan should end up having some kind of confrontation if Rick finds out what happened. He already knows those guys who attacked him earlier were the ones Morgan allowed to leave. When he finds out that Morgan still hasn't learned and has put even more people in danger, he probably won't be happy.
Also: I felt like going through some of the older seasons again after watching that "Shane beats the shit out of Ed" clip. It's pretty cool to see how much some of the characters who are still around have changed since season 1.
