Fili had been following Bilbo's moves closely since they left Bag End, finding the hobbit not only interesting but also very attractive. Hobbits were so different than Dwarfs, he was curious about Bilbo and wished to talk with him and know everything about him. The thoughts that were occupying his mind lately werent helpful at all to stay distant from Bilbo, and this wouldn't be necesary, Fili thought, if Thorin wouldnt had started to act better towards the hobbit, the young dwarf realized his uncle was somewhat attracted by Bilbo.<br/><br/>Fili saw Bilbo and Thorin talking earlier that day and he wanted to know what was going on between them so he decided to wait and see what they had planned. When everyone went to sleep he did as well but he kept himself awake, and stood still under the blanket until he heard Thorin talking to Balin and walking away.<br/><br/>He waited for a moment until Balin got lost in his thoughts or maybe fell asleep again and very slowly he got up, making sure Fili was really sleeping, he crawled half way out the camp between his sleeping fellows to then walk the rest to where Bilbo had disappeared.<br/>Fili couldnt follow Bilbo, there were no signs of a hobbit's trail but he quickly found his uncle's footsteps and followed them.
