He doesn't, you have to take him to Kakariko village and see the shaman
You give Ashei's sketch to Prince Ralis, in the Graveyard in Kakariko Village, where you got the Zora armour.
In Twilight Princess, Princess Ruto is not there. If you remember in Ocarina of Time, she became a sage. A new generation flew by and now it's a prince and a queen. Not a king and a princess.
After you guide Prince Ralis to Kakariko Village, follow Queen Rutel'a Sprit to the Graveyard. She will open a path which will lead you to her husband's grave where you will receive the Zora Armor.
When you first bring him he is being taken care of by Beth and Luda in the inn. However when he gets better you'll see Beth standing by herself looking at the graveyard. Go into the graveyard and go to the spot that Ralis's mother gave you the underwater outfit.
Telma has no genetic relationship with Ilia. However, Telma was the woman who took Ilia in when she lost her memory and helped her andPrince Ralis escape to Kakariko Village.
