I want to make a request for the runt of the litter. I don't know but looking at all the situations the winchester siblings went through, I would like to read an episode of closure. Where only anna speaks, strong, fierceful, yet full of emotions, and the brothers would listen. She would break down but convey how she really feels about everything they have been through, about how much respects she hold for her brothers, how she always looked up to them. Her perspective of her brothers being the world saviors, self sacrificing. How anna is desperately protective of her brothers, although she's the youngest. How much anna want her brothers to have a normal life.
This whole situation might be caused from an argument, which occurs in settings portraying the brothers vs anna. Ending with a sweet reconciliation between them 3 (almost to make us cry). If you can write this, please do.
I love your writing. Take care.
