This season of Dexter has been a little disappointing to this point, but this third episode introduces a character who not only will play a bigger part in weeks to come, but may play a part in getting this drama back on course. Dexter meets the former abductee (or was it cohort) of a long-ago serial killer, and she’s played by Yvonne Strahovski, formerly of Chuck. His first meeting with her throws him a bit – and I expect that may be a trend.
