Meanwhile, fans are assured that they have not seen the last of Bellamy. Even though Gabriel, Echo, and Hope chase after Bellamy's abductors, they fail to stop them.

"The 100" showrunner Jason Rothenberg confirmed TV Line that there is a lot to Bellamy's storyline. His disappearance is going to play an important part in the current storyline of the final season. The story of many characters will revolve around their attempts to find and save Bellamy.

"It's the mystery people are trying to solve. It's the thing that's going to be driving so many of our characters this season — to find him and hopefully save him," Rothenberg says.

The showrunner assures fans "we will see him again."

"Bob [Morley] asked to take some time off this season, and we honored that. We were able to write around it," he added.

Meanwhile, he talks about Clarke's struggles to keep the Sanctum together.

"Clarke has not been reacting emotionally to the death of her mother ... and suddenly it crashes down on her. She's trying to keep Sanctum together. That's her mission and she's going to do it. But her friends are looking at her like, 'It's OK to grieve. You lost your mom.' We realize at the end that it has been eating away at her, and it comes bursting out. She is great in that scene — and in the scene that follows it on the balcony. I think she crushed that, too. There was a standing ovation on set when she did that," he explained.

In addition, he said that season 7 will delve deeper into Sheidhea's quest for power and dream to take place on the throne.
