[Henry knows Frederick's unable to stop working for the sake of the greater good. That's just how he is, and sorry, but he's going to take advantage of it for now. There's the reluctance to be anything but helpful, and then there's the need to survive. Henry follows Frederick's well-meaning advice.]

Nothing foolish, got it. No funny business. I'd never dream of it. [Not really, BUT... he'll look into minding his manners.] Good thing you're warm, Frederick. That really makes this easy. The warmest thing I've felt all afternoon. It kinda... Sleepy...

[What purpose is there to remain entirely alert? he wonders. The cold overwhelms him, and the warmth soothes him. Henry gives in to the conflicting elements by zoning out and allowing Jesus Frederick to take the wheel. Maybe he should be more worried about the circumstances he found himself in just moments ago, but Henry seems totally at ease, somehow.]
