It was no secret that Thorin had trust issues with most people outside of his own kin, but something about Bilbo had drawn him in. A big part of it was that Bilbo had done more than enough to prove himself trustworthy. And then there was the fact that Bilbo had stuck beside the Dwarves more than once on their journey even when it might have suited him better to betray them. Bilbo is one of the most loyal people that Thorin had ever known, so that really did make it easier for Thorin to be so open with him.
As always Thorin welcomed the kiss to his lips, and he placed his hands lovingly on Thorin's lower back, pulling him a little closer.
"I certainly don't have any intentions of going anywhere, but yes happier thoughts. Lead the way" he added, as he turned towards the door, but then he waited patiently for Bilbo to take the lead.
