Just Add Chuck - S2.E3

The girls have their first interaction with Chuck, but it quickly becomes clear that he is suffering from some sort of amnesia. He doesn't remember anything about the Pluot Festival in 1965. Grandma and Mama P think he's lying and can't be trusted, so the girls cook a trust spell that helps Chuck adjust to the modern day - but it also unlocks some of his memories from 1965.
