Rewatch S5 Lindsey eps. I still think Lindsey's stated motives for coming back were specious and kinda lame. Fortunately, the fanfic writer can fix that!
Gil is fascinated. Catherine has a shotgun & protects totally freaked out Nick. Sara & Warrick are off somewhere else, maybe with Brass? Greg is suddenly an authority; he's got a massive collection of zombie movies. Ecklie we can kill off. Yes.
