Sara, Johnny and JJ are visiting her father in an Elder Care facility. They come across Bruce in his physical therapist mode assisting a patient in the use of a walker. The walker is being used on an area rug covered hall. This is a tripping hazard and would not be present in a place where the elderly would be likely to stumble and fall. The assisted living staff would know to not have such a danger around.
Johnny says that when he and Sarah were dating that she was always late, and he missed the beginning of The Empire Strikes Back in the theater because of her. But that movie was released in 1980 when Johnny was just 12 and it has been established that they did not start dating until around 1996.
