You could make a strong argument that Alias peaked at the tail end of its second season, and from The Two onwards the journey of J. J. Abrams’ series is all downhill.
There is merit to that but it isn’t precisely fair. The Two is a solid reestablishment of Sydney Bristow as a character and the re-conceptualised series as a concept, triggering the first half of a third season which ultimately consumes itself but starts out heartily, with a fascinating new mystery surrounded by a revived and re-developed set of character dynamics. Penning this opening episode, if not directing as he did the Season Two barnstormer of a finale The Telling, Abrams sets the stall for Alias to come. This is a soft reset of the show, one designed to follow through on the structural changes established after Phase One. In previous reviews, we talked about how Alias spent the rest of the second season moulding itself around a mid-season explosion of the series’ initial idea. The Two is a response to that.
The Two could not have functioned in the manner it does if Phase One had taken place at the end of the second season, as was rumoured to initially be the plan. SD-6’s collapse would have triggered a third season which began with Arvin Sloane as the villain, and much of what happened at the end of Season Two likely would have taken place in the first half of Season Three, with one key difference: no Lena Olin, who had rejected the opportunity to reprise her role as Irina Derevko after her one season stint as a regular. Given how awkwardly Season Three has to write around Irina’s absence, try and imagine the cluster of post-Phase One, pre-The Telling episodes without Irina. They would never have worked as well as that last third of Season Two does, however fractured and galloping the storytelling might be.
Given Alias detonated Sydney’s role as a double agent halfway into the previous season in order to streamline the series, The Two has the space in many ways to do just that. It attempts to provide a rough template for the new season to follow.
