Meanwhile, Lara Means (Kristen Cloke), examining evidence relating to Johnston's murder, discovers that Peter Watts (Terry O'Quinn) had suppressed infrared post-mortem photographs.
The Elder agrees, and similarly decides to hold off on testing which would reveal if an artifact in Johnston's possession was an authentic piece of the True Cross.
Black's wife Catherine (Megan Gallagher) is approached at her new job at Aerotech International by a colleague who reveals that the company is part of the Odessa network.
Meanwhile, Black visits Catherine's boss, Clear Knight (Kimberly Patton), experiencing visions of Nazi Germany after seeing a watercolor painting in her office.
As the Elder conducts a funeral for the Old Man, a car bomb kills his assassin, while Odessa's Paraguayan headquarters is destroyed, and Knight's company is raided and closed.
[4] Morgan has noted that the plot for "Roosters", and the previous instalment "Owls", grew out of the internecine conflict seen within the Millennium Group in "The Hand of St. Sebastian", an earlier second-season episode he wrote with Wong.
Handlen particularly highlighted O'Quinn's performance, reflecting positively on his increased importance in the series and noting that "portrayal of an acolyte struggling with the demands and doubts of his faith does as much for Millennium as Henriksen's work".
[10] Bill Gibron, writing for DVD Talk, rated "Roosters" 5 out of 5, calling both it and "Owls" a "dense, deceptive set of shows" which focus on the personal and ideological conflicts between their characters.
[11] Robert Shearman and Lars Pearson, in their book Wanting to Believe: A Critical Guide to The X-Files, Millennium & The Lone Gunmen, rated the episode one-and-a-half stars out of five, calling it "dull and flabby".
