For a show concerned primarily with generating and disposing of corpses, sometimes the most shocking twists on How to Get Away With Murder involve good old-fashioned betrayals. For three seasons its characters have built the shakiest of friendships, but it still packs a punch when one of them turns on the others. Most recently, in a thread teased through flash-forwards, one prominent character will kick the bucket and Annalise (Viola Davis) herself will be implicated when her surrogate son Wes (Alfred Enoch) snitches on her to save himself from different murder charges. In this exclusive sneak peek, watch Annalise process the notion that one of her own has betrayed her.

Knowing that HTGAWM lives to mislead us, should we take this plot line at face value? Or is there something more going on with Wes and Annalise? It wasn’t too long ago that she enlisted her students to shoot her as part of a larger cover-up, so who’s to say she didn’t put Wes up to falsely snitching? But seeing as we’re about to find out exactly which character will wind up #UnderTheSheet, it’s safe to say this roller coaster is just getting started.

How to Get Away With Murder airs Thursdays at 10 p.m. on ABC.
