Yvonne Strahovski (“Chuck”) is set to reprise her role as serial killer Hannah McKay on season eight of Showtime’s “Dexter,” premiering June 30.

She tells EW:

I have known for what seems like FOREVER and have been busting to tell people. I was very excited to have been asked back!

[Hannah] is coming back to shake things up for Dexter a little… just to add to the turmoil.

Hannah McKay became romantically involved with Dexter Morgan after learning about his Dark Passenger in an almost fatal manner. By the season’s finale, she had been arrested for the murder of a true crime author out to expose her, but faked a seizure at the courthouse to escape from going to prison.

Strahovski, best known for her role as CIA agent Sarah Walker on the NBC comedy “Chuck,” will next be seen in Lakeshore Entertainment’s I, Frankenstein, a futuristic re-imagining of Mary Shelly’s classic novel adapted from Kevin Grevioux’s (”Underworld”) graphic comic.
