Why do I love Fi? Because Fi, out of all the guidance characters in Zelda, is actually made to know all that stuff. Navi and Tatl are just fairies, how would they know what a certain Dungeon Boss does? Midna may be the Princess of the Twili, but she's definitly not the kinda of person who would know everything about your foes. The Owl? That Owl can go fly into Death Mountains Crater for all I care. Fi is made by the Goddess to know everything about everything. I won't say Fi is not annyoting from time to time, but at least she is actually a good character to back it up (Yeah, I said it. toss them Pitchforks at me for liking Fi over most other Companions, still like Midna better, cuz Midna). And think of it this way, Midna went back to her own world and closed the only portal, but I dount Twili are immortal and thus she'll eventually die, Navi probably died in the Lost Woods, like Tatl did somewhere in Termina with Skull Kid and Teal. Fi never really dies. She's just sitting there in the Master Sword, waiting for a new master to pick her up, but never able to emerge again. Just being alone untill the Master Sword is destroyed and she is killed. Just let that Sink in. Fi will remain in the Master Sword untill it breaks and she dies, just remembering her days with the Original Hero from the Sky. Now that's just sad
