There was actually a Morgan St sign that they kept showing. They are really cockteasing people with that guy, with his potential for truckloads of crazy.
The blatant horse metaphor is probably how alexandria goes down. The gay already tipped off his long-con with his comment about burning down the barn with the one exit. When his secret gay army shows up all they have to do is block the gate and start some fires and he'll have his revenge for being shunned. His gaydar already led him to Daryl, who will be safely out recruiting on his LOUD ASS COME KILL ME DEATHCYCLE when the hetero purge goes down.
That or it's just a red herring with the "look what happens when you stop running and trap yourself inside walls!" or "omg which character is going to be Buttons!?"
Was the priest even at the party? Can probably cross (heh) him off your dead pool until he gets his own "remember me?" preview clip.
