Continuity mistake: When the three ladies are trying to sneak out of Morty's house Annie has glasses on. In the next shot when they are about to climb into the window cleaning contraption she doesn't have glasses on. Next shot they are back on again.
Suggested correction: Please rewatch; here's a SCENE CLIP. Annie looks over the bannister at 00:14, and it cuts to a shot of the street below the scaffold. At 00:17, Annie lets out a blood-curdling scream and as she throws her head back, pay attention, because the bridge/rims of her glasses have been thrown upwards to the top of her forehead, and within this same shot as she turns her body, the eyeglasses bridge/rims fall downward back onto her nose, right before Brenda grabs Annie's coat lapel. Annie's glasses never vanish.
Corrected entry: When Brenda is reading the card from Cynthia, the camera shows a shot of the card and it is written to Annie, not Brenda. Annie's name appears several times.
Correction: While Elise has a cleansing mask on her face, when she looks down at the mail pile on her floor we see the 1st of Cynthia's mailed envelopes, addressed to Elise. It cuts to a closeup of the 2nd of Cynthia's mailed envelopes, addressed to Brenda, and Brenda opens her envelope, gasps as she reads silently. It then cuts to the 3rd of Cynthia's mailed letters - a closeup of Annie's hands holding the letter addressed to her, as she reads and says "omg." Then, there are a few shots of all 3 women, each silently reading their own Cynthia letters. At 00:33:43, Annie reads aloud to her mother, part of her own letter from Cynthia. Please, rewatch this scene, there are no continuity issues whatsoever.
