In many ways, After Six can be considered indicative of the kind of fan-baiting series Alias became in Season Three after the daring apogee of Full Disclosure, a sign of what it runs arms-opened toward in the latter half of the season.
Crossings established that Syd & Vaughn were not going to remain apart as per the new, Julia Thorne-era paradigm, and that the writers were determined to find a way to untie the difficult knots of storytelling that had replaced the UST of the early seasons with a trauma-driven, grief-stricken change in circumstance preventing them being together. Work would need to be done in order to return them to a romantic state, work that takes the rest of the season in all honesty, but Alias would be intent on giving the fans what they wanted: the SVR (Syd-Vaughn Romance). Season Three, as a result, begins in After Six to deliberately angle the series away from Syd & Jack’s relationship as the dramatic focal point, as it is when Alias operates at its best, toward what becomes a knotty quadrangle.
Having Lauren turn out to be a Covenant agent is not a bad twist in and of itself, indeed it makes a modicum of sense on several thematic levels for Alias as will become apparent in what happens to Vaughn’s character at the back end of the season. However, it very deliberately is a convenient way to lessen the problematic moral realities of Syd & Vaughn becoming romantically involved when one of them is married. After Six begins to explore this but everything is offset by how immediately pantomime Lauren becomes as she partners, both literally and sexually, with Sark across this episode. She wears dark eye shadow. She tries out revealing lingerie. She seduces Covenant bosses and savagely murders them. In perhaps one of Alias’ most chilling moments, Lauren watches Sark strangle a man to death while having a casual, loving phone check in with her husband, talking about making them some supper.
After Six, therefore, begins the recalibration of Alias into a more simplistic series driven by sex, betrayal and more traditional forms of spy plotting. It is sporadically entertaining but, at this stage, that’s about all.
