When Fili was 30, he decided he was in love with Ori.
The very first person he told was Kili. In fact, the only person he told was Kili, who responded by laughing so much, he fell off his bed and tumbled onto the floor.

He did, however, regret instead hitting the mirror, breaking it, and earning himself a lashing from his uncle.
