Bellamy’s (Bob Morley) fate was left ambiguous at the end of The 100 season 7, episode 5, “Welcome to Bardo.” Bellamy’s whereabouts and whether or not he was alive has been a driving force in the final season after he disappeared early in the season 7 premiere.
Bellamy’s absence is a bit awkward for The 100, as he’s been a central character since the series began in 2014. When the actor, Bob Morley, requested time off from the show, he was canceled by the Bardo folks, beginning the plot in the direction of exploring the other habitable planets connected to the Eligius III mission.
After a few weeks back, Bellamy finally appeared in The 100 season 7, episode 5 alongside the Anomaly Stone in Bardo, trying to free his sister, Octavia (Marie Avgeropoulos). His appearance ends in a somewhat confusing ending, as one of the Bard’s soldiers throws a kind of grenade.
After the explosion, Bellamy disappeared and the Anomaly closed, raising the question of what happened to him. Echo (Tasya Teles) and Octavia react as if Bellamy was killed, but that’s probably not what happened. Instead, he likely traveled to one of the other planets in the Anomaly stone.
Before Bellamy disappears, the Anomaly opened up behind him. While it was a mystery in season 6 of The 100, season 7 has explored the nature of the Anomaly as a wormhole, acting as a bridge between the worlds of the galaxy.
After noticing that the soldier was looking for the grenade, which seemed to create a flash of light rather than a large explosion, Octavia yelled at Bellamy to jump back across the “bridge”, as many characters call Anomaly. As the light blinded the characters and the camera, Bellamy could have jumped or fallen back into the Anomaly to escape.
The 100 have never been afraid to kill beloved characters, but these plot twists have always brought about a confusing turnaround for fans. This scene wasn’t given as much weight as that, so it’s likely that it somehow survived and made it to a new planet.
