As of yet, Link is never reunited with Navi. It probably won't happen, either, unless a game with the same Link from OoT is made.</
Link is on a Quest to find his old friend Navi after parting ways. (Navi is his fairy from Ocarina of Time)
In the beginning of the game there is a flashback. It shows Zelda giving Link the Ocarina of time for his journey to find Navi. In the beginning you see Link on his horse in the woods. That is his journey to find Navi until skull kid brings him to Termina.
It is unknown whether or not Link is reunited with Navi. It is up to the player to fill in the blank. I can only assume that after saving Termina, Link continued on his quest to find Navi. In Twilight Princess, the Hero's Shade is rumored to be the Hero of Time(or just Link) which also encourages that if someone go into the Lost Woods without a fairy, you turn into a Stalfos. This encourages that Link never found Navi or Tatl ever again and wandered into the lost woods WHICH, turned him into a stalfos. In Twilight Princess, the Hero's Shade helps out the current Link with hidden skills. In Hyrule Castle Cemetery, underneath a sacred tree(a great deku tree)the cursed hero of time supposedly lays.
Navi
The Navi master is your father.
Navi leaves link at the end, why else would he get a different fairy in the next one. Navi leaves him because he is no a real kakiri child
Link doesn't talk because he's cool like that! Another reason is that he was swinging his sword around trying to kill Navi his fairy companion when he accidently chopped off his tongue. He didn't want a new one so he lived his life not talking ever since.

the answer is she actually does leave him. don't forget only kokiri get fairies and link isn't a kokiri. the great deku tree only sent navi to protect link until the evil was gone.
If you mean that by leaving link when battling ganondorf (1st part) then it is because ganondorf uses part of his triforce power to make it so Navi can't lock on to him. all you have to do for that part is him the energy orb with your sword. In other words ganondorf uses his power to keep navi out of the battle. If you mean why does navi leave after the game ends, ts because navi was only meant to join link and help him save hyrule, she cant stay with him because hes a hylian not a kokiri, but im sure they talk sometimes.
Navi is 5' 11".
