Bilbo realized that he wasn't the same as being Thorin's kin. Fili, Kili, other Dwarves. He still felt close to Thorin, though. Closer to him than he felt for some of his own kin. He felt understood by the Dwarf. Which was part of the reason he was glad that he and Thorin were under the same roof. It made it far easier to adjust to such a strange place.
Perhaps all three of them could eventually be under the same roof.
"I am sure it will be fine," Bilbo said, offering Thorin a small smile. Perhaps it wouldn't taste like the ale from home, but it would still be ale. That's what Bilbo cared about -- the fact that Thorin had at least attempted to recreate something from home.
"Do we have half-pints?" he asked. Because he knew drinking a full pint would cause him to be more inebriated than he would like. Not that he thought he would be unsafe if he were. "I would take a full one if we do not."
