Sunshine begins Day Two of Training with the help of Aidan and with Lucio watching as she helps a spirit, Eddie Denfield, move on.
Sunshine sees Eddie lingering by Meghan Water's locker. He's had a crush on her for years and regrets not taking his chances while he was alive. He does not want to move on without saying goodbye even though they can only see commotion in the hallway.
This scene is significant because Sunshine is the only luiseach known to have the power of being able to see the spirits and feel what they went through as she helps the move on. She is probably going to need to use this power for something extremely important later in the story that only she can accomplish.
