Thorin did notice the smile on his friend's face, and it brought a smile to his own as well. He had a feeling what awaited him should he ever return home, so he was grateful for every single chance the two of them got to spend time like this together. It was something that would get him through those rough times, and he certainly hoped that Bilbo felt the same way.
Normally, Thorin wasn't a very physical person when it came to affection, but with Bilbo he found it to be welcome. So, he nodded his head slightly and allowed the hand to his shoulder to linger longer than it would with anyone else.
"That sounds like it will be wonderful. I look forward to trying it" he replied, before taking his own seat now that the two of them seemed to be ready for enjoy their little feast.
