Another moment of pure Grimesenberg goodness, as he continues on his take-no-sh*t warpath with the line: "Do you have any idea who you're talking to?" Chances are, yes, but we have no idea who Rick is talking to. The editing very cleverly makes it look as though it's Morgan he is pointing the gun at, but that's almost certainly a classic bit of trailer misdirection from the producers. It may be another member of Alexandria he's threatening, but more likely (or hopefully) this is one of the Wolves in this scene, which would mean that by this point they're an established threat to Rick and co.
