It’s our first Murder-free TGIT, and it will be at least seven months before the show returns for its sophomore year. So it’s time to start theorizing.

Rebecca (Katie Findlay) was found dead in the closing moments of the How to Get Away with Murder finale. The obvious culprit was Frank (Charlie Weber), whom viewers had just learned murdered sorority girl Lila Stangard. But for that very reason, he might be too obvious an answer.

Annalise (Viola Davis) was keeping the truth about Rebecca’s demise a secret from Wes (Alfred Enoch), which could make her another candidate. However, when Davis appeared on Jimmy Kimmel Live the night of the finale, she said that an alternate finale ending had her character walking down into the basement and finding Rebecca dead while still tied to the chair—which seems to indicate Annalise was not at fault.

Who else does that leave? Wes was super emotional at the end of the finale. Some might attribute that to him questioning whether he was really justified in killing Sam (Tom Verica)—but what if Wes was so convinced Rebecca had killed Lila that he, in turn, killed his girlfriend? Feeling like he’d been played the whole time would make anyone snap. Plus, the puppy has already committed murder once—and Rebecca even thought he could’ve killed his own mom. So it doesn’t seem far-fetched that he could do it again.

As for everyone else: Any member of the Keating Five not named Asher (Matt McGorry) could also have a motive for silencing Rebecca once and for all. Asher could be protecting his fellow Keating Five members, only to pull a Keyzer Soze that reveals he’s orchestrated everything throughout the whole series. Bonnie (Liza Weil) could’ve finally become the killer we’ve all hoped she is. The recipient of the mysterious “Eggs 911” text could have killed her, fearing Rebecca would reveal some dark secret she’d been keeping for him/her. Nothing is too crazy at this point! (And if you’d like to use any of these ideas, Pete Nowalk, you know where to send the check.)

Now it’s your turn to share your theories. Who do you think killed Rebecca—and why?
