and was highly respected by other military men deployed there. Colby stated that although it was evident from the aftermath that Ian had been involved in an operation, "you never saw him." Ian is brilliant and loves his work. During their first encounters, Ian and Charlie clashed: Charlie did not believe in using guns to solve problems and disdained Ian's dispassion about killing. In contrast, Ian thought Charlie's mathematic approach was too academic for real cases, and his scientific viewpoint made his objections to Ian's attitude hypocritical. He even went so far in their early acquaintance as to call Charlie's math "voodoo." Despite their early rancor, however, the pair have come to mutual respect for their different expertise and even a kind of friendship. He backed Don up to their superiors regarding Don taking the Crystal Hoyle kill-shot, which took place in "

". It is heavily implied in "Two Daughters" and "Pandora's Box" that Ian used interrogation techniques, including physical force and borderline torture, to get information from a teenage accomplice of Crystal Hoyle. It is also implied that Don has seen or heard of Ian using such techniques before. Given that Ian's superiors were more concerned with discussing Don shooting Crystal Hoyle than Ian's borderline interrogation methods, it is likely that Ian will not be disciplined or will only be disciplined lightly over this incident. With the kill shot through the cab windows of a pickup truck, executed in "Pandora's Box," Ian hopes to be moved up to the third-best shot in the U.S. Edgerton did not appear in season four but returned in the premiere and finale for season five. At the end of the season five season finale, Ian goes on a date with Nikki Betancourt. During season six, Ian is accused of murdering one of his informants and taking money from a drug dealer that Ian had arrested years earlier. At the time, Don and the rest of the team struggle to believe Ian's innocence, especially after Ian takes Colby hostage. Eventually, they realize Ian's intentions and work to have him released from prison. Edgerton returned for the season six finale in a cameo appearance where he made an arrest and expressed disappointment that he was not invited to Charlie and Amita's wedding. According to Lou Diamond Phillips in an interview with TV Guide, Ian was supposed to be a closed-ended role. Members of the cast and crew wanted his character to return, so the writers expanded Ian's expertise. Since then, Phillips remains a cast and crew favorite.

). Initially a one-time guest appearance, Oswald quickly becomes a fan favorite and reappears in a second episode, in which Charlie attempts to persuade Oswald to enroll at CalSci. Oswald was originally supposed to be a one-time role. For the episode "Hardball", series executive producers/co-creators Nicolas Falacci and Cheryl Heuton created Oswald to represent the geniuses who fail to receive a formal education. For Oswald's educational background, the writers decided that he taught himself math. Heuton and Falacci developed the character of Oswald Kittner for another friend of series regular David Krumholtz. When the friend did not audition, Krumholtz suggested Baruchel for the role. After seeing Baruchel's performance, Heuton and Falacci modified the role to include some humorous lines and add Oswald's voice. Although Oswald was a skateboarder, Baruchel never rode a skateboard and spent some time learning from the stunt coordinator and a skateboarder.

Fans enjoyed Oswald's appearance on the show and continued requesting Oswald's return. Falacci and Heuton, along with the cast and crew, were amazed by Baruchel's performance, and Falacci and Heuton decided that Oswald was to be a recurring character.
