The father's monologue where he finally gets a spine in the car.... jesus. Jesus. This ending is crazy amazing for all of the characters, brings suspense in every scene, and ends with a final punctuation mark - family. Siblings. The crazy dynamic in between and ghosts. Insane.
Nelly's monologue was crazy good, too. The writers know how to do this right, and paired with the talent's stunning performances - it's art.
