Bilbo was rather comfortable like this. Sitting like this, with Thorin. It was nice and comfortable and just right. He hadn't always been this comfortable with the Dwarf, but he was definitely glad that he was at this point in time. Thorin was the one he had grown closest to, out of all the Dwarves. Even if their relationship had been rocky in the beginning.
To say the least.
He did notice the blush that appeared, but he wasn't going to give him grief about it. That was the last thing that he would do, to the point where giving Thorin grief over it didn't even cross his mind. He just placed a hand on the other's leg, patting it lightly. Briefly.
"I don't believe I will be as fond of anyone else as I am of you -- in the same way I am of you." Of course he was being honest and truthful with Thorin -- he wouldn't have it any other way. There would always be a place in Bilbo's heart for the Dwarf King.
"I couldn't bear it if you were sent home," he admitted.
