I didn't think episode two was as bad as episode one, except for Enid's newfound medical skills. There's no way a teenage girl saws off her friend's arm as decisively and coolly as she did by herself without any formal training and more extensive field work beyond stitching up cuts with supervision. Most of the rest of the episode was character development and relationship drama. Oh, and why is there such a shortage of water for the workers? They're building a bridge over an effing river!
