In this episode Phoenix finally gets validation on his wild claim that Glenn was alive. Also he complains about the show some more, mostly about how they don't have a duty at Alexandria in which people stab zombies in the head all day to keep their numbers down. Instead they just keep adding more to the inside of the walls which actually makes Alexandria smaller every single day. Figure it out, people. Balloons. A big part of this episode is balloons. You'll have to watch to figure out why.
