Conscious operates in quite a formative space, not just for Alias but many of the works from J. J. Abrams production house that would overlap and follow it.
After the grim but effective exploration in Breaking Point of Alias’s position externally as a post-9/11 series rocked by the traumatic mass hysteria of terrorism on American soil, Conscious moves inward. It contextualises many of the thematic ideas not just of the third season but of Alias as a whole, specifically the inherent duality behind the concept. Sydney Bristow spends her life being two different people, herself and whatever ‘alias’ she adopts week by week on mission. When the narrative structure disappeared after Phase One that enabled this, Season Two brought in the Helix doubling technology and established, particularly by The Telling, two sides of a psychological join in Allison/Francie – the darkness and the light. Season Three brought that inherent duality into Syd’s character herself through her missing time and Julia Thorne, apparently an externalisation of the darkest impulses that the show has worried about since the beginning.
It’s worth noting in many ways that Alias has always been a little bit obsessed with the idea of the virtuous American mother/wife/girlfriend being not what they seem, and in Syd’s case it also extends to the idea of the hero being corrupted. The revelations about Laura Bristow, the lionised, dead before her time image of the perfect American wife, shatter that visage with the reality of the duplicitous, enigmatic Irina Derevko. Allison Doren murders the innocent, unaware Francie and works to corrupt the CIA’s operation from within through assassination and brainwashing, prepping Will Tippin as a ‘Manchurian Candidate’ in the making (fitting given the character was built on cinematic conspiracy templates). Julia Thorne is the ultimate expression of the fear about Sydney, that she might be an Irina in the making, or a programmed assassin, or a 500 year old prophesied bringer of mass destruction. Conscious is Alias’s psychological method of coming to terms with this anxiety, especially after Breaking Point.
What Syd finds as she enters the recesses of her subconscious manages to both forward the key narrative arc of the third season while making explicit the core thematic idea of the entire show: the greater enemy is within, not without.
