Isn't it strange that no one ever confronts Rook about .....? [DAV Spoilers all]

HEAVY SPOILERS!!!!!!!!

YOU HAVE BEEN WARNED!

I can't be the only one who finds it strange that no one ever confronts Rook about Varric being dead, right? Especially at the beginning of the story, where Neve or Harding walk into the room and Rook is talking to themselves. Or during various group conversations, where Rook is staring off into the distance because they see Varric there.

I think the companions definitely should have brought this up at some point. Especially Harding. It’s so strange that it’s never mentioned. I mean, in a way it fits, since the companions barely seem to care about Rook as it is, but the real reason is probably that the revelation of Varric being dead has to come at the endgame to highlight just how "devious" Solas is.

Or maybe I just didn’t fully understand this plot point?
