context_page_description: "Os" is the 16th episode of the third season of the American science fiction drama television series Fringe, and the 59th episode overall. The episode centered on the Fringe team's investigation into a series of robberies of the element osmium, which they connect to a scientist who is able to defy the laws of physics.
  "Os" was written by Josh Singer and Graham Roland, while Brad Anderson served as director. Along with Ruck, the episode also guest-starred Jorge Garcia in a brief cameo as a security guard.
  On its first broadcast in the United States on March 11, 2011, an estimated 3.76 million viewers tuned in, giving it a 1.5/5 ratings share for those between the ages 18–49. Critical reception to the episode was generally positive, as multiple critics noted that Ruck was well-cast as a scientist just trying to help his son.
context_section_description: The episode was co-written by co-executive producer Josh Singer and executive story editor Graham Roland, while former Fringe producer Brad Anderson directed it.
  The return of the William Bell character to the series was inspired by Leonard Nimoy from earlier seasons. In his first appearance on Fringe in the first season finale, "There's More Than One of Everything", Nimoy requested that a bell be placed on his desk so that his character would be able to ring it as a play on the character's name.  When the writers considered how to bring Bell back for the third season, they recalled this mannerism, and wrote it into the larger mythos, being the means by which Bell's mind emerged from Olivia's at the end of this episode.
  On March 3, Entertainment Weekly reported that actor Jorge Garcia would be making a cameo appearance in an upcoming Fringe episode. Garcia, who previously starred as Hugo "Hurley" Reyes from J.J. Abrams' Lost, appears as a Massive Dynamic guard that is smoking a bong with Walter at the start of the episode. Alan Ruck guests as Dr. Crick, the person behind the floating bodies. Ruck was approached by the show's producers having envisioned him for the role. Ruck described the character, "He is no dummy... and he stumbled on to something and he is trying to figure out a way to use it. Ultimately he would like to use it for good, but in so doing he causes a lot of damage. So I guess you can say he's obsessed. And this particular point in time where the episode of Fringe starts, time is fleeting and he's just... under the gun." On his character's possible reappearance, Ruck commented, "I think not... Technically yes [he could come back], but probably not."
  As with other Fringe episodes, Fox released a science lesson plan in collaboration with Science Olympiad for grade school children, focusing on the science seen in "Os", with the intention of having "students learn about meteorites and ways of finding them."
