Things take a turn for the worse in the upcoming episode of "The 100" season 4.

Titled "Gimme Shelter," next week's episode will see Clarke (Eliza Taylor) head to the island to save more people. However, her arrival immediately takes a turn for the worse. Elsewhere, Bellamy (Bob Morley) is still in Arkadia as he continues to keep further tragedy from happening in the area.

Last Wednesday's episode saw Clarke work with Bellamy and Roan (Zach McGowan) in an effort to find a way to save as many individuals as possible. The group encountered yet another major setback when they lost their fuel supply after risking their lives to get it. However, Clarke still managed to squeeze in some quality time with her good friend Niylah (Jessica Harmon).

While the forthcoming episode's synopsis does not give too much away, Taylor recently spoke to IGN about what's next for Clarke, Bellamy and the rest of the characters. Although Roan and Clarke's alliance will be slightly weaker after their failed plan, their respect for each other will push them to continue the mission to save mankind.

"It's very hard to preserve this alliance for obvious reasons," the actress said. "No one is particularly happy about this new team that they've formed. But at the end of the day, there's a lot of respect and understanding of the fact that they both want what's best for everyone."

Taylor also teases some tension between her character and Raven (Lindsey Morgan) when they meet again at Becca's (Erica Cerra) lab. "It's tough because they're in such a confined space together," she explained. "Obviously tensions will rise. Clarke and Raven this season are really not seeing eye to eye. They will definitely have their moment."

In other news, "The 100" scored a season 5 renewal from The CW last week. The early pickup comes just over a month after the post-apocalyptic drama debuted its current season. With only six episodes in, the series is a strong performer on delayed and digital viewing, with 70 percent jump among all viewers and an 86 percent increase among the 18- to 49-year-olds demographic.

The fourth season of "The 100" airs every Wednesday at 9 p.m. EDT on The CW.
