[It hadn't been his goal to make Leon guilty for once. He doesn't even miss the way he responds, though Baymax picks up on it when he looks back at the two boys. Even if he's ahead, Leon will have noticed Baymax continually looks back to check on Hiro. He's been trained to look after his patient at all costs and Hiro's grown so used to it he thinks nothing of it.]

Dunno. In case you haven't noticed, it's not really in our design to do everything that's expected. [He huffs lightly.] Baymax was never programmed to understand non-physical wounds. He taught himself. Downloaded a whole database and educated himself. [On grief, specifically. He doesn't think he needs to spell that out for Leon though.]

...and anyway activating him was kind of an accident. I couldn't get him to go away after he showed up, but I'm kinda glad he didn't listen to me.
