After the fight with Gannondorf, Rarru and Sonia turned Zelda back from a dragon to hylian. You (link) caught Zelda and you landed in a lake.

A week after you saved her, you and Zelda are at home eating a dinner and Zelda is telling you about her journey in the past

"So I met the first king and queen.." she started, you didn't have the heart to tell her that you already knew about all this, though it's not like you speak anyways..

"Link?" Zelda asks when she noticed you staring off into space
