Lincoln (Ricky Whittle) and Octavia (Marie Avgeropoulos) both defied their leader's orders in the season 2 finale, and the unlikely couple will wind up back with the Arkers as season 3 begins.

"Octavia and Lincoln are back in Camp Jaha, which is a very awkward situation for Lincoln, because he's a Grounder - and at the end of the day so is Octavia," Avgeropoulos told TV Line.

The girl under the floor may have an allegiance to the Grounders, but her only family lies with her original clan - the Sky People.

"The strongest alliance is family, is Bellamy - Octavia is the only one [of The 100] with a sibling, so she's in a really difficult situation," Avgeropoulos said. "We'll see what position she takes in Season 3!"

At least Clarke, for the moment, is no longer residing at the lake front base. Avgeropoulos previously told The Wrap that Octavia and Clarke are still at odds over the bombing at TonDC. Having the two in close quarters probably isn't the best idea, not with everyone still dealing with the fallout from the Mount Weather massacre.
