[A trusted companion. That hits very much close to home. Two he knows immediately spring to mind; one from where he came from, who turned out to be a little less trustworthy than he'd hoped, and one he has met here, who just might be different... though so much more fragile.]

Thank you, your Majesty. I shall try to remember your words.

[That said, the boy straightens. King Arthur looks well for someone who has been brought back from death. Walter can see no signs that would be cause for immediate concern.

Naturally, he's still curious as to how the man was brought back. But, that sort of question isn't one he's inclined to ask publicly. Too many people could get ideas. Too many things could go wrong.]

I should be getting back to work now. [There's much to be done, and he for one isn't interested in delaying that.] I'm sure there will be more to talk about next time we meet.
