Yep. The cutscene back when Zelda was sitting with Sonia, at the table and the tea cup. It explained what Sonia is really good at. Rauru is the Light, and Sonia is the Time Magic. She mentions about thinking of whatever anything to anybody like a memory, to return to the state of where it was. They were foreshadowing the idea of how Zelda could be returned for a good part of the game. She couldn't go back on her own, but very strong time and light magic is exactly what is needed to apply that aspect on Zelda, like a memory, and coaxed it back to the earlier point in its time. Like a tea cup.
