Season Two
The New (Para)Normal

Book Marks the Sprite

As the two traveled across town, Ollie lost contact with the Story Sprite, believing that he let the people of Brighton down, especially Molly. Molly tried to convince him that ghosts aren't bad by listing examples of all the good things they ever did, including the fact she would be a friendly ghost as well. Despite knowing how positive Molly is, Ollie digressed, saying that ghosts are incapable of being nice and no one should suffer from it. Seeing Ollie's treatment to the people of Brighton compared to ghosts, Molly began to sing a song about him as ghosts shouldn't be a threat.

The two soon went to an ice cream shop, where Molly asked Ollie why he believes ghosts to be evil if they hadn't actually done anything harmful to him. That was then Ollie explained that the reason his family hunts ghosts was because one attacked his father, Reuben Chen, during his childhood.

As Molly learned that Ollie's way of bringing peace to the world is by getting rid of ghosts, she expressed disappointment as she believed that it would be impossible to change Ollie's mind. But hearing about Libby's experience from the Story Sprite, Molly learned that all she had to do is just make Ollie understand the ghosts.
