Revenge has cut through the Weeds and tracked down Emily Thorne's mother. Well, really Amanda Clarke's mother, but still.

ABC sources confirm that Jennifer Jason Leigh has been cast in the highly-anticipated role of the woman long presumed dead by her troubled daughter. The first season of this thriller concluded, of course, with the discovery that Mrs. Clarke was still alive.

As you might expect, the character has been described psychologically damaged, dangerous and a bit of a loose canon. And to all of those who have only seen Leigh's comedic side on Weeds over the last couple seasons, rest easy:

There's plenty of time to pick up Single White Female before Revenge Season 2 premieres in September.
