Selling The OC’s Alexandra Jarvis may be used to going by her last name, but her first name was revealed to be Rachel during the second season of the series. Alexandra, who typically goes by “Jarvis” due to the fact that there are 3 other Alexandra’s in the OC O Group office, was known for being part of a duo during Selling The OC season 1. Working with Alexandra Rose, Jarvis would door-knock with her partner in order to get better listings, and while their strategy worked, their relationship began to crumble between Selling The OC season 1 and season 2.
