What is the name of the character played by Yvonne Strahovski in Dexter?

The character played by Yvonne Strahovski in Dexter is Hannah McKay.

Hannah is introduced in season 7 as the former accomplice of spree killer Wayne Randall. When Randall’s buried victims become relevant to a reopened investigation, Miami Metro Homicide seeks Hannah’s DNA and testimony. Her history is complicated: she says she did not commit the murders, but the series reveals that she has used poison and other methods to kill people who threatened or abused her.

Hannah becomes one of Dexter Morgan’s most important romantic relationships. Unlike many people in Dexter’s life, she recognizes his capacity for violence and does not respond to it with ordinary fear. Their relationship forces Dexter to question whether his identity is controlled entirely by his so-called Dark Passenger.

Viewers sometimes mix Hannah up with other major women in the series, especially Debra Morgan, Rita Bennett, or Lila Tournay. Hannah first appears in season 7 and continues into season 8; Yvonne Strahovski also became widely known for playing Sarah Walker in Chuck.
