"The Walking Dead" returned to AMC Sunday night and the episode wasted no time catering to one location or person. Rick is back in action and in search of allies to help him take down the Saviors.
While you were reveling at being reunited with Rick and the gang as they bounced from one camp to another to assemble an army against Negan, you may have missed a few key moments and references the episode alluded to hinting at potential larger problems to come.

How closely were you watching this scene when Gabriel drove away from Alexandria in the episode's opening minutes?

At first glance, it may have looked like he turned on Rick and the gang and took off, but that may not be the case.
Another person revealed themselves to be on the passenger side of the vehicle as Gabriel drove away.

Who is the mystery man (or woman)? Did they force Gabriel to purge Alexandria of its goods? Perhaps it's the same mysterious person we saw skulking around the camp in the mid-season finale or someone from the group Rick just ran into at the episode's end. Maybe they're both connected.
