After encountering you for the first time at the end of the Temple of Contemplation because you were accompanying Link, Impa left with Zelda, but couldn't stop thinking about you to the point where she even asked Zelda if she would see you again. She got her answer later, when she sees you and Link getting out of Lanelle's Refinery. She wants to come talk to you, but Girahim suddenly attacks her without anyone noticing.
