This issue raises more questions than it solves! Which is great, as it makes me want to keep reading. The well creature is more tricksy than ever and Sam is, if not dead, then close enough. I hope he stays that way. Physical violence is always less interesting to me than head games, and the well creature (I suppose I should call it? him? Zack, but it feels like Zack is only for the moment) seems as if it will excel at those, which is promising. 

Finally, I realise that Nina has not been raised on the horror genre, but if Sam isn't dead she's got two kids who failed to kill him and she needs to teach them follow-through. Almost, in this case, is not good enough, and that's a horrifying note in itself to end on.
