Cameron's interest in House supposedly subsided as she began a relationship with Chase, although it resurfaces occasionally with flirtations and Freudian slips; in the season 4 episode "Ugly", Cameron lets slip to a documentary team that she loves House. In "No More Mr. Nice Guy", when House is believed to have neurosyphillis, Chase asks her directly in front of Foreman and the other fellows if she has slept with House, to which she ambiguously replies "It's none of your business". Chase thinks she did; however, later, when they are in private, she says she did not. In season 4, Cameron also dyes her hair blonde. Early in season 4, House, who was told by Dr. James Wilson (Robert Sean Leonard) and Dr. Lisa Cuddy (Lisa Edelstein) that Cameron and Chase moved to Arizona, finds her in the ER after finally discovering that they were still working at the hospital. House tells her that she was an "idiot". When Cameron asks if it was either the hair or where she was working, he said where she was working, stating that her hair made her look like a hooker and that he liked it.
