Disclaimer: I do not own The Hobbit
Bilbo spent most of the day getting Thorin coffee and taking notes on things, all while trying to be oblivious to Fili and Kili. The two mischievous brothers, when they weren't pulling his hair or mocking him to his face, they were eyeing him from afar while whispering and sniggering. The plane ride home was no less grueling and the car ride after that was spend reviewing his notes, making sure he had a good understanding, both of what he was expected to do and of the mines. As they pulled to a stop outside his house he looked between the three and he knew why he felt the click. This was very probably where he was going to click; there would be his people, his friends. He smiled and shook Fili and Kili's hands before, lastly turning to Thorin.
"Despite my fear of flying, I had a wonderful day. Thank you very much for this opportunity and I hope, in the coming time we will both prosper from working together." Bilbo said smiling. Thorin hadn't even made eye contact with him, the whole time. Bilbo would have offered his hand if he'd thought there was any hope that the advance would be replied to. Instead he made a curt and awkward bow before hurrying inside.
