There's this film I saw a month ago called Mother, and it's about an elderly mother and her autistic son. The son is arrested and accused of murder, and it's up to the mother to solve the mystery over the course of the film to prove his innocence.
Spoiler alert: it was the son who actually committed the murder. He was legit looking for China, and the girl he was stalking told him to back off and called him a retard. He responded by throwing a huge rock at her, killing her.
If Chris was ever in that situation, would Barb go through hoops to clear his name, or would she lie on her couch and do nothing?
