When they were in the warehouse, before preppy was eaten alive, he made a comment about Glenn has "done this before" or "knows what he is doing" or something to that effect. What was he referring to? That Glenn somehow manuevered the zombi.. er, walkers/rotters/biters/roamers/deadheads into that cage and away from them? Think I missed something there.
He was talking about Glenn hearing the zombies and deducing those inside were stuck behind something because they didn't come when he banged on the door.
(sound of walkers and rattling)
Glenn: They are stuck behind something.
Aiden: How do you know?
Glenn: I don't. But they aren't here.
(advance and find the walkers behind the fencing)
Glenn: Clear.
Aiden: Clear.
Aiden: You know your stuff.
