Season four, though one of the consistently better years of The X-Files, really suffered from helter-skelter scheduling and last-minute episode switching. Thus, a wholly self-contained episode like "Unrequited," airing just weeks after the momentous events in "Memento Mori," seems out of place and pallid in comparison.
The x-file in this case has to do with invisibility, specifically the paranormal ability of a POW escapee to induce some sort of blind spot in the eyes of others. I didn't really get it, and the writers probably didn't either, but the theme is appropriate: this is an episode largely forgotten amongst the season's pinnacles and for good reason.
As with numerous other Howard Gordon episodes, political overtones float around the script with the subtlety of a brick and a window. Nathaniel Teager, a man left for dead in Vietnam, has returned to the US to carry out his agenda to murder the men responsible for his predicament. Excess preachiness notwithstanding, don't forget this is a theme largely borrowed from season three's "The Walk," which featured basically the same scenario with a few blanks filled in differently.
The generals are not likable characters, the character of Teager is never explored (Peter Lacroix has few spoken lines in the entire episode), an opportunity to explore Skinner's character is all but wasted - despite a contrived mentioning of his time in Vietnam slapped onto the end. Somehow Marita Covarrubias shows up in the mess, reminding us how much Gordon likes to shoehorn his deep throats into plots that don't really necessitate their presence. Even Larry Musser, notable for his sheriff roles in "Die Hand Die Verletzt," "Jose Chung's From Outer Space" and "Chinga," falls flat in his static role of Denny Markham. And somehow at the end of the episode, notable for being one of the series' shortest, it is hard to meet the preceding events with anything but indifference.
There is one scene that I did like, when the agents arrive outside of Markham's compound, and Scully, scanning the perimeter, briefly spots Teager standing in the background. This is truly a creepy scene, and adds a distinguished touch that is unfortunately lacking just about everywhere else.
Overall, this is a fairly skippable episode. There are no particularly interesting characters, the plot has been seen in other episodes, the script is filled with political clichés and just seems far too reminiscent of other Gordon episodes. For the forty-something minutes I invested in this, I feel as though my reward was unrequited.
