The 100 Stars Promise Shock and Tears in Season Finale, Tease Bigger Villain for Season 4

At the CW Upfronts Thursday, two stars of The 100 were on hand, as Marie Avgeropoulos and Isaiah Washington walked the red carpet to talk about the season 3 finale and what's to come on season 4.

The pair were in good spirits, but had a warning to fans of The 100. When asked what emotional response fans will have to tonight's season finale, they were both quick to answer.

"Tears," said Washington. "Shock," says Avgeropoulos.

Isaiah Washington added a more in-depth warning, telling Comicbook.com, "Cover up your screen with some bubble wrap, because you're gonna throw things at your television. I guarantee it."

Both actors seemed excited for season four of the series, which will once again be a mid-season premiere on The CW. They talked about how they've never shared a scene together, and how despite their differences, "They're both outcasts," and they might actually get along. A suggestion of just how from us at Comicbook peaked their interest, in fact.

Washington said that Jaha might still be redeemable, if not out of true forgiveness, then out of necessity.

"There's a threat at the end of this season that's much bigger than Alie," Washington teased. "One person asked me how is it possible that my character could be forgiven for all the things that he did in season 3. When you see what the threat is in season four, you're going to need all hands on deck. It doesn't matter what these characters did in season 3 because the threat is so big."

The 100 season finale airs Thursday May 19 at 9pm on The CW.
