In “The One That Got Away”, Camille’s brother Theo cleared out Linus’s apartment. Theo stole all his smart appliances. Linus doesn’t even have a dishwasher, oven or washer/dryer.
Linus isn’t going to get any help from his landlord, especially since a tenant complained about Linus being too noisy. (That was probably Theo’s fault, too). Linus needs to replace all the appliances in his apartment, but he doesn’t have the money.
Cameron makes it clear that he doesn’t want Linus as a roommate. After a terrible college experience with a roommate who liked to study without any clothes on, Cameron vowed to never have a roommate again.
