I think Morgan's "clear" focus is his own self-acknowledgment that he's crazy in the head. It's like they saw a reflection in each other which ultimately caused Rick to admit to Michonne and vice versa that all of them are just going crazy in the head.
With the season finale approaching, I hope morgan plays a twist role in the conclusion to woodbury with him either dying in the process of saving carl as an act of redemption for not saving his own son, or just a gun blazing maniac.
Come to think of it, there was also a masked person on the episode where the governor attacked the prison. The masked person was the one who crashed through the fences and unleashed a horde. Who the hell was that?
