"Killing Eve" [1] returns for its fourth and final season on 27 Feb. in the US, with the series landing on BBC iPlayer in the UK the very next day. The beloved series, starring Sandra Oh [2] and Jodie Comer [3] sure knows how to grab our attention, and as a result, viewers have a lot of questions about the upcoming series.

For fans of BBC's compelling spy thriller, the teaser trailer's arrival on 28 Dec. was a pretty big moment, because they'd been waiting a long time for any updates about the show's return. Between scenes of Eve (Oh) attacking someone with a bat and Villanelle (Comer) dressed as a creepy clown, it was clear that the new episodes were going to take the show to another level. "Do you ever think what might have happened if we hadn't done what we did?" Fiona Shaw's character, Carolyn, says in the 28-second clip. "People like us aren't made for happy lives with happy endings."

The official trailer arrived on 1 Feb. and it felt like Christmas morning all over again. The latest trailer offers a terrifying glimpse of what's in store for the final season, which will consist of eight episodes — and unsurprisingly, it's drama, deceit, and even more drama.

"Do you know the fable about the scorpion and the frog?" Oh's Eve asks Comer's Villanelle in the trailer. "They both die, because the scorpion can't change its nature." On that note, we're anxiously twiddling our thumbs as we wait to see how Eve and Villanelle's story ends. Watch the latest trailer ahead.
