Remember the coupling on Friends? Ross loved Rachel since season one; Chandler and Monica became a thing in season five; and Phoebe met Mike in season nine, one season before the end of the show.
Why am I mentioning this? Because this episode of Bones reminded me how much of a fifth-wheel Cam is.
She's a private person, so it's understandable that her family life and romantic affairs aren't shown every week like Brennan's and Angela's are. But it's one thing for Cam to have an off-screen boyfriend who is rarely mentioned and another thing for her to be secretly dating an intern.
How suspended does one's disbelief have to be to imagine that Cam and Arastoo have been together for any length of time? Nothing in their interaction prior to this episode has prepared us for this. It seems like the writers decided that Cam needed a new love interest since her previous boyfriend hadn't been seen in two years and saddled her with the first available recurring character.
Wendell wouldn't do since he already had a fling with Angela. Clark is no good since he's supposedly in a committed relationship.
Finn is nineteen and dating Michelle, and although the writers aren't genuinely invested in Cam's love life, even they wouldn't relegate her to that.
Fisher? That would be even more unbelievable than Arastoo. Which brings us to Arastoo. Of the interns, he's certainly the most plausible. But that doesn't make their relationship in anyway believable.
