Obviously, very spoilerific.
Harry and Lara are in the search for Justine. I wondered, given that Harry knows the walker name, why can't he summon it?
(I am very angry thinking that apparently Harry is not going to find Justine in a year (at least) and by the time the baby, if Justine allows him/her to live, will be born and spend their first months of life with a literal monster)
