She wants something brought to her, does she? How fortunate then that Han, seeing Frea sink deeper into Brienne's hold and knowing that he's in the dog house, is ready to go for the walk that will fetch them something. Although since he's not a mind reader, he doesn't know that she's thirsty. His intent was to go questing for s'mores ingredients ...

"So, those s'more things you were talking about before, Frea ..." He begins. "I think I'll nominate myself to get up and get the components for that, unless either of you ladies has an objection."

Besides, he wanted to find Barton at some point anyway. Might as well be now. He can tell him what the hell makes up a s'more too.
