There's actually a pretty decent C-plot running through this ish, where Kid E has been summoning the dead for his teammates (because that's the best way to get them to like him), and he asks Cassie if she wants to talk to anyone. She obviously really wants to, but she, apparently, has gotten over that cult thing and knows better, and finally eventually tells him that she absolutely does not want to see anyone from her past and if she ever asks him later he should refuse her.
It's almost like McKeever wants us to start respecting her.
