When Joan is talking to Stevie at the end, Stevie's hair changes. It goes from in front of her face to behind her ear without her moving it.
You can't get into high school without your Social Security Number, so how is Stevie in school?
In the scene where Adam introduces Bonnie's work to Mrs. Girardi in the art room in school, there's an inconsistency. When the scene switches between Adam and Bonnie, Adam's sleeves are rolled up in certain shots and down in others.
When Joan walks into the park, Cub Scout God crosses behind her and goes off screen-left. But then he instantly appears on Joan's right and says "Hi, Joan!"
Grace: Okay, you can choose to forget this or I can inflict brain damage.
Adam: How the hell did this happen?
Grace: Ask the little friend in your pants.
Female Custodian God: Hi there, Joan.
Joan: Oh god...
Female Custodian God: The one and only.
Joan: Didn't we use to be good people?
Kevin: I think so – what happened?
Electrician God: (to Joan) What you witnessed was the power of the truth.
Joan: Isn't it your job to 'let there be light?'
Electrician God: It's everyone's.
Joan: Woah. When did you get here?
Electrician God: I'm always here, Joan; even when you can't see me.
Will: Do you know a hot dog has meat from a thousand different cows in it?
Carlisle: And I'm grateful to every one of them.

God's nametag: A. Vatar
Avatar is the Hindu word for "God in human form". Though frequently used by commentators on JoA to refer to the various appearances of God, I think this is the first time that the word has actually been used on the show.
