Trish tries to carry out Kilgrave's command to "put a bullet in your head." But his specific command was to put a bullet in her *skull*.
After Jessica tosses Robyn's fliers away, Robyn states that she spent 3 hours at Kinko's. In 2004, FedEx bought Kinko's, and was renamed FedEx Office. People will often continue to refer to things by a well-known prior name, such as Chicago's Willis Tower still being called the Sears Tower. Robyn knows Kinko's became FedEx Office, but still thinks of it as Kinko's out of habit.
In the flashback, the horse stops right beside the sidewalk, but after Jessica jumps off the roof the horse is suddenly in the middle of the road. She also lands farther away from the building than she should have, considering she only stepped off the roof, rather than jumping. However, this is then shown to be a dream or fantasy, and as such doesn't have to adhere to realism.
