"I see." That makes sense, given the state the others, and while he's a little disappointed he won't be able to meet her, he's not inclined to bother her after all that either. Too know she's safe is enough, he's fairly sure, and really both he and Hythlodaeus know the entire search was an excuse anyway.

Which leaves him in an odd spot; he's not terribly inclined to just leave, wants to check up on the others once things have settled a bit, but likewise things have likely not settled in the five minutes he's been gone and his brother likely isn't in a place where he'll be more happy with being fussed over. (Not that he ever is, but Thanatos at least recognizes that he's working and now is not the time.) So after a moment of consideration he gives a little laugh and a shrug.

"Well, if you're sure she's alright, then I suppose Idon't have anywhere to be. Perhaps instead of you keeping me company, it could be the other way around?"
