4-04.1 View from in front of Nat continuing to walk with her arms behind her head with her expression nonchalant. Jane jogs a little to catch up to her.
JANE: My dad read in the paper that the police are saying your dad skipped state.
NAT: Makes as much sense as anything else.

4-04.2 Jane looks away a little wistfully.
JANE: I wonder if he's alright out there.

4-04.3 Jane collides with Nat from behind where she's stopped walking.
JANE: Oof!

4-04.4 View of Nat from behind, her fists now clenched at her sides. Jane stands off to the side looking startled and upset.
NAT: Wherever he is, I hope he burns in hell.

4-04.5 Nat starts walking towards the camera again, her torso taking up the entire foreground. Behind her we see Jane looking confused and upset.
