The Arker's displeasure will be the direct result of Clarke's (Eliza Taylor) decision to skip out on Camp Jaha, according to showrunner Jason Rothenberg. Unfortunately, this won't be a feeling that dissipates after a solid night's sleep.

"He understands why she had to go, but he definitely resents her for it," Rothenberg announced on Sunday after Morley and Taylor made similar comments at Florida's Supercon.

Bellamy, Monty (Christopher Larkin), and Clarke were all complicit in the Mount Weather massacre, and it's safe to assume Bellamy thought the trio would handle the fallout together, both in the emotional arena and on the Earth's perpetual battlefield. Clarke, however, took off on a walkabout and didn't quite specify when (or if) she would be coming back.

For his part, Bellamy will continue to help lead the Sky People. As the third season progresses, the eldest member of original The 100 will be in for a bumpy ride.

"Well, he's going to have a rough season, let's put it like that," showrunner Jason Rothenberg via Periscope. "But we're going to love it, going to love him, for it."
