Tonights episode:
Echoes
With Nadia’s life on the line, Sydney must race to bring down former nemesis Anna Espinosa (Gina Torres, “24”). Meanwhile, Vaughn’s inner demons surface when, in order to help Sydney save Nadia, he’s forced to confront his own former nemesis, the slippery and deadly Mr. Sark (David Anders).
Sark, Anna Espinosa, and the return of the rimbaldi device. I'm so fucking excited about this one. Its also supposed to be a two-parter, so we get a cliffhanger ending.
