couple of questions re the ending *SPOILERS*
What happened to Paul? Why didn't they eat or drain Paul, who was still alive after the attack? And on that subject, why did Francis phone Paul, leave that message, and not arrange to meet him somewhere? Francis liked Paul, but his call led the man to his dreadful fate.
Did not get the whole thing about Francis and his being let early out of the box. If Francis was in the box at all, then he's been eating people/drinking blood his whole life. The really young ones are indiscriminate in their attacks; hence, the box. So why does Francis throw up after eating person, which he's surely been served all his life? Why the refusal to kill, when he's seen his family do it constantly, and he's been the recipient of those kills? And why does he suddenly change, kill a girl he likes, and get all okay with himself and his siblings after he has done so?
