Last week's How to Get Away with Murder ended with a big development: They found Sam's body... or did they?

"I can't say," Karla Souza, who plays Laurel, tells TVGuide.com. But! "There's another clue in the woods that they find and that leads to an arrest."

This turn of events will drive a wedge between Annalise and the Keating 4 — particularly Laurel, who has turned out to be the calm one, always one step ahead of the police.

"I think Laurel has come into her own ... and she doesn't freak out when there's no need to freak out," Souza says. "But she starts seeing Annalise sort of turn on them. ... If she had to choose between saving them and saving herself, it's pretty obvious she'd save herself."

Who do you think is taking the fall for the Keating 4?
