No stranger to thinning the herd, The CW’s The 100 is poised to lose another original cast member.

Isaiah Washington, a main part of the show’s cast since it premiered on The CW in 2014, will not return as a series regular in Season 5, TVLine has learned exclusively.

“We’ve been incredibly fortunate to have Isaiah Washington on The 100 for the past four seasons,” executive producer Jason Rothenberg tells TVLine. “He’s brought so much to the role of Jaha, and we love working with him.”

Washington’s character, Thelonious Jaha, has undergone a radical transformation since we met him three years ago. After being stripped of his chancellor title, Jaha became a lost soul, eventually finding salvation — or so he thought — via the promises of an evil technological being known as A.L.I.E. Following her defeat, Jaha attempted to redeem himself, most recently helping his people gain access to a top-secret bunker that could save them from an impending nuclear death wave.

But don’t go throwing dirt on Jaha’s grave just yet; at this point, it’s unclear how Washington’s character will be written out of the show, nor is it known whether the actor may appear again in a guest-star capacity.

New episodes of The 100 air Wednesdays at 9/8c on The CW, with the fourth season wrapping on May 24. Drop a comment with your thoughts on Washington’s departure below.
