Continuity mistake: Jessica arrives to see the doctor, and she wears boots. Both step out and walk towards the barn. A shot later, she is suddenly wearing high heels.
Suggested correction: This is listed for the wrong episode; it belongs to "Funeral at Fifty-Mile" S1-E22. But it's also a duplicate of a mistake that's been listed since 2017, here: https://www.moviemistakes.com/entry235059.
