Jon tells Babis he should go ask Soraya about the torso, figuring it's not his problem if she doesn't let the kid look at it.

But Babis's general air of seeming drunk and being in good spirits, coupled with the clues that have come out so far and how much he was into chatting and how readily he discussed his interest in the design, means that they all thank him for his time (sincerely, in all three cases), wish him a happy birthday again (Sansa and Jon both say "nameday"), and move on!
