Fili had not been able to find Kili in some time. Knowing now, what he does, of his brother's death back home and his own, he knows that returning there is not an option, for he will not find his brother there. Only in the Halls of Mandos in the afterlife that awaits will they meet again. His heart aches for such knowledge, but he knows he cannot simply stop.

He had been following her, wishing to speak to Tauriel. After all, if anyone else would know of whether Kili had been seen, she would know. He followed her through the door carefully, disturbing a stone or two to give her the warning that he was approaching, smiling sadly for the movement of her hands.

"You must allow me to help," Fili insisted. "I'm quite the expert."
