If How to Get Away With Murder has taught us anything, it’s that Annalise Keating (Viola Davis) will go to almost any length to protect her group of law students-turned-co-conspirators. In this exclusive sneak peek of Thursday’s episode, Keating proves that includes a surprise visit to threaten A.D.A. Emily Sinclair (Sarah Burns), who has been blackmailing Asher Millstone (Matt McGorry) with private information.

"He sent me on his behalf," she tells Sinclair, effectively cutting off her communication with Millstone. "I admire your ambition. You see an opportunity to grab headlines, to make the big boys upstairs notice you, but you're making a rookie mistake."

Annalise threatens the assistant district attorney, with whom she’s already thrown down once before in court this season, accusing her of witness tampering and intimidation.

"I make one phone call and the press will make you out to be an overzealous, law-breaking prosecutor desperate to take me down," she warns Sinclair. "Why? Beats me. But the reporters will come up with theories: jealousy, egomania, racism…"

In the end, Annalise gets her way, but not without a parting shot from the A.D.A.

"I’ll lay off Mr. Millstone, but only because we still have the Hapstall case together," Sinclair cautions. "I look forward to destroying you in court."
