Like the previous issue, it's a quiet one, almost entirely lacking in superheroics (there's a dream sequence, and then a rescue of Lila from a crashed plane at the end.)
Sam spends most of the issue blundering into things (without even needing to fly), so that's quite an apposite codename for him. He offends Lila by assuming that a gift she proposes to give to his mother is stolen; they later reconcile after he and his brother save her life. And as the eldest son of the departed Thomas Zebulon Guthrie, he assumes that he's the "head of the household", which is (a) fairly silly, on account of him probably not being 18 yet and having a perfectly functioning adult mother, and anyway (b) hardly a thing he can manage from Westchester. He realises (b), but his answer to it is initially to move back in and, I don't know, suddenly start being the man of the house. Some sense is talked to him, and he returns to Xavier's in the end.
Joshua (Jay) is worried, too, about becoming a mutant himself, and then reveals at the end that his mutant power is singing. I... was not expecting that, and this seems to have been entirely swept under the rug, since he goes on to become Icarus.
