In different scenes, Loki's shirt collar changes from a button-down to a straight one.
At approximately 23:40, Loki walks into Brad's cell. The fire hose is on the left side of the screen and the phone is on the right. When it switches to Brad's (upside down) point of View (POV) the room is upside down, but hose and the phone have not switched sides, as they would if your view turned upside down. The hose should then be on the right side of the screen and the phone should be on the left.
