Dushku will appear in the ninth episode of the third season as a very sexy woman who works for Matthew Keller (Ross McCall).
The series follows con man Neal Caffrey (Matt Bomer) and FBI agent Peter Burke (Tim DeKay), who team up to solve crimes. Although Caffrey has found a love interest in Hilarie Burton's character, Sara Ellis, creator Jeff Eastin adds that Dushku appears [spoiler alert!] after Neal and Sara have broken up. "She ends up having a short fling with Neal," he says.
Although the former Dollhouse star is only scheduled for one episode, Eastin says that her appearance leaves room for her to come back.
Season 3 of White Collar premieres Tuesday at 9/8c.
