Lily is forced to bring Carole with her to visit Ella. She is shocked to find that Carole is actually pleasant around Ella. On her bike ride home, Lily has an unexpected encounter.

Levi makes an appearance and has an interesting proposal for Lily. Carole is still....Carole-like. Lily's plans to visit Ella get unexpectedly changed.

Lily's parents are completely unsympathetic to her problems with Eric following her around--and are making her apologize to him for being rude. After talking with her Dad, Lily discovers a door unlocked that shouldn't be. Where will her curiosity lead her?

Eric follows Lily around everywhere. She and Corrie try to get rid of him, but he keeps turning up. Is he just socially awkward or is there another reason?

Carole joins Lily's group in Legendary Literature. Her bad attitude shocks the other students--not a big surprise. What is surprising is another new student starting school on the same day as Carole. What are the odds?

It's Carole's first day of school, but it doesn't start out smoothly. Ginnie is too sick to take her, so Matt will have to. But there are problems for the start--the King's security team doesn't want him leaving the house, Matt doesn't know much about OtherWorld, and Carole's being her usual grumpy self. Oh and Corrie still wants to know why Lily's been grounded.

Lily follows Carole out the window and lands herself in the middle of a LOT of drama. It seems unmathematical, but things with Carole get even worse.

Carole's first evening in OtherWorld isn't going well. After a rough dinner--which Carole ate extremely quickly--Ginnie blames Lily for not trying hard enough. Is it mathematically possible for the night to actually get worse?

Calo and Lily arrive at the North Pole and meet Carole. She is....not what you'd expect Santa's daughter to be like.

She'll be living with Lily and her family while she does this. How will Lily handle this new change in her life? And how will it be seeing Calo again?
