Barbie points out that the list of potential careers for graduates of her technical institute includes at least one job she didn't have (writing fortune cookies).
Raquelle tells Barbie that she spared no expense buying her birthday present. She proceeds to give Barbie a compact mirror. Nikki points out that it comes free with a $600 makeup kit, which Raquelle apparently decided to keep for herself.
