The continuing evolution of Alias across its first season is increasingly paralleled, as it should be, by the evolution and development of protagonist Sydney Bristow, as Color-Blind again returns to the central theme of not understanding or knowing who you truly are, growing lost within yourself deep inside a world with no clear delineation of black and white, or right and wrong. What Roberto Orci & Alex Kurtzman’s second script for the series does, and Alias does for the first time, is frame Sydney’s character journey through that of a guest character.
One of the difficulties in serialised storytelling to the degree Alias has deployed thus far is that it does not particularly encourage the use of the main guest character. TV shows of old, traditional series which tell a contained episodic story and move on, often framed a one-off character as key to the story being told that week. Murder mystery series, such as Murder, She Wrote or Diagnosis Murder, cop shows such as Law & Order or CSI, even science-fiction series such as the Star Trek spin-offs of the 1990’s and shows such as The X-Files, all of them frequently utilised a major guest character to weave a narrative around. With a serialised show telling an ongoing tale, it becomes a lot harder to stop and anchor a story around someone the audience doesn’t care about, and who’ll be gone next week.
Martin Shepard, who we briefly saw played by John Hannah in Reckoning previously, does not entirely anchor everything in Color-Blind but this is unquestionably the first episode of Alias to give a character who is not one of the main cast ensemble an arc of some fashion; in this case, Shepard being reminded of his tragic past as a brainwashed assassin who ended up killing Syd’s fiancee on the programmed order of SD-6, and his journey toward finding some escape and peace from that. The reason it works, and Alias is able to do it, is precisely because it factors into Syd’s psychology along the way. Shepard is a character in his own right but his existence is designed to sketch in more aspects of who Syd is, and her own journey in accepting Danny’s death.
