He doesn't recognize the name "Voltron", but there are a lot of gods in the multiverse and he's not particularly religious, so that's not a huge surprise to him. "Paladin of Voltron" is a phrase he can understand perfectly fine without knowing who Voltron is. This woman is a holy warrior of some kind, which is awesome as far as he's concerned, and he'll address that at some point, but for this good polite boy, the big thing that immediately sticks out is...

"Oh!"

This woman is royalty and here he is, sitting on his butt on the end of a bed, casually talking to her about spiders.

"Shoot, I'm so sorry, Princess, I didn't realize--!" He stands right the heck up and does his best to bow respectfully without rearranging his feet, because one of them is still being stepped on by a spider claw, and he doesn't want to disturb Daisy. "Should I--? Um, I'm sorry, we can get another room so can have this one to yourself, um...!"

The closest to royalty he's ever come is that infernal earl asshole, but being appropriately polite to him was a breeze because he'd gone in expecting the royalty. He has no idea how to deal with this surprise royalty situation, and honestly if this princess wanted to smite him for not being polite enough before finding out her status, he'd totally get it.
