Much like Glenn is wanting to stay behind in order to do the right thing, we find relative newcomers Annie and Scott also wanting to stay behind, although thats because they dont want to slow the group down. Despite this scene serving to make Heath seem like more of a leader and to flesh out his character a little more, the whole go on without us thing doesnt quite sit right. Sure, Scott has been shot in the leg thats a decent injury and a reason why he may slow the group down but Annie had a bit of a trip over a stray tree root. Is that really enough of a fall to write yourself off and insist that your friends go on without you?
