Haley (in Alexia's body) gets a hickey from Kyle when they are kissing in her car. When she sits down at the dinner table next to her sister, the hickey is on the right side of her neck. In the kitchen, when Alexia (in Haley's body) is yelling at her, it is on the left side of her neck. When they are at school and Alexia (in Haley's body) puts concealer over the hickey, it is on the right side of her neck again. It looks like the makeup artist couldn't make up her mind...
