Yeah it was. I really did not see him NOT knowing what the cure/how to cure the walkers is. Everything he said being a lie just caught me off guard. When Abreham punched him though, that was freaking great. You know he's wanted to do that for a long time, dude is annoying. Think he really fethed him up though with the last punch (smacked his head against the fire truck).
And what about that town! There were a LOT of walkers there. It's like the whole town got together to die.
