The CW released its official synopsis for the fourth season seventh episode of The 100. Its title is called, Gimme Shelter and here is what the description says about it. *Be aware that the synopsis will hold spoilers. Continue at your risk.*
The 100 Gimme Shelter official synopsis:
THINGS TAKE A TURN FOR THE WORSE — Clarke’s (Eliza Taylor) arrival on the island quickly takes a turn for the worse. Meanwhile, Bellamy (Bob Morley) tries to avoid further tragedy in Arkadia. Paige Turco, Marie Avgeropoulos, Devon Bostick, Lindsey Morgan, Christopher Larkin, Richard Harmon, Zach McGowan, Isaiah Washington and Henry Ian Cusick also star. Tim Scanlan directed the episode written by Terri Hughes Burton & Ron Milbauer (#407). Original airdate 3/22/2017.
The synopsis contains dim spoilers as usual, but my speculation that something rather worse happened then the burning in Arkadia. Although, I can’t really picture anything much worse.
