Flashback sequences became an important element in two episodes this season, "Lineage" and "Suspect". Greg Beeman, who directed "Lineage", worked off the same inspiration as Ken Biller, who used John Sayles’ "Lone Star" when writing the flashback sequences for the episode. Beeman tried to visually shift from the present to past without any effects shots; this included changing night to day in the same shot, and removing/inserting actors from shots when they were out of the view of the camera. In his directorial debut, Ken Biller was met with the challenge of creating flashbacks for all the scenes that retold the event of the attack on Lionel. Biller had already seen Beeman's take on flashback scenes from his work on "Lineage", but Biller wanted to do something different. Alongside director of photography Glen Winter, Biller opted to shoot all the flashback sequences on 16 mm color reversal film, which would give the flashbacks a "grainy, dirty look" that Biller thought gave an interesting quality to the flashback scenes.
