[Honestly, he's a little at a loss for words for a moment, on both of the points Arthur brings up because -- hey like he can blame Aramis or Arthur for becoming close, it's no surprise. And yet it makes him think once again of the difference between himself and that man, not in jealousy but a kind of wonder at the way he goes about things. Lancelot's own feelings are complicated and hard to express, not because it isn't true but that even with Merlin he had some trouble putting it into words.]
Arthur... [He nods, just so, because he ultimately can't deny that.] I understand why you would struggle with the best way to talk to me about this.
