Question 1: what happened to the kid? Did he left him all alone?
Question 2: how did he know sensei's address?
Question 3: why did his ex-wife leave him? He looks and acts alpha as fuck and unless he's a psychopath with hidden hand fetish and explosion abilities I don't think anybody would do so.
M'lady I don't want to be snarky but if muffin with this kind of density exists nobody would be able to stand near it without being pulled and spaghetti-zed, let alone digest it.
