I don’t know all the rules to psychic powers in this world. Like, could someone specializing in telekinesis know a little bit of mind-reading? (I always assumed that’s what Teru did when he cheated at tests). Maybe they go into that later on, I dunno.
Here Mob’s using a bit of empathy by accident and digs into inner feelings rather than ones on the surface. Mob has such a low opinion of himself I figure learning that someone cares enough to be willing to die for you would be pretty overwhelming.
(Please don’t remove the description on this or it’ll make zero sense. :’’’D )
