I can just see Kyle in my Au worrying about his health. Especially if he gets sick or if his kgs fluctuate due to stress or other factors. Eating would definitely be a more regular discussion between these two.
Kyle: You know, you've been at this for hours. You sure you want nothing to eat?
Baron: I'm perfectly fine, Kyle.
Kyle: You sure, Boss? You haven't eaten since yesterday morning. That's 35 hours.
Baron: If I'd require nutrition I would have already gone and gotten it. The time span is irrelevant.
Kyle: Not even a snack? I mean, I could get you something. Kitchen's cooking dinner regardless, so it's really no is-
Though, as you can see, these would have the potential to get rather...heated.
