"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 (Alan Ruck) 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.
The Fringe team is called to the scene of a robbery of a metal depository; the body of one of the thieves, shot by a security guard, inexplicably floats off the ground, while a second culprit has gotten away. They find that the thief has taken off with a supply of osmium, one of the densest elements, and an autopsy later reveals that the dead thief's body is filled with the metal. Tracking a security card on the body, they enter a warehouse where they find the second culprit, dead, along with the bodies of several more people, all of them paraplegic. Walter (John Noble) notes that the physical properties of osmium (both gravitational and thermal) have been reversed, and by melting the osmium collected from the first victim using liquid nitrogen, they detect the presence of the rarer element lutetium, typically only present in meteorites.

The first season of the American science fiction television series Fringe commenced airing on the Fox network on September 9, 2008, and concluded on May 12, 2009. It was produced by Bad Robot Productions in association with Warner Bros. Television, and its showrunners were Jeff Pinkner and J.H. Wyman. The first season introduces a Federal Bureau of Investigation "Fringe Division" team based in Boston, Massachusetts under the supervision of Homeland Security. The team uses unorthodox "fringe" science and FBI investigative techniques to investigate a series of unexplained, often ghastly occurrences, which are related to mysteries surrounding a parallel universe. FBI agent Olivia Dunham is portrayed by actress Anna Torv, while actors Joshua Jackson and John Noble play father-son duo Peter and Walter Bishop. Other regular cast members include Lance Reddick, Jasika Nicole, Blair Brown, Mark Valley, and Kirk Acevedo.
The season contained 21 episodes, although only 20 of them aired as part of the first season. The unaired episode, "Unearthed", was aired a few days before the episode "Johari Window" as a special episode during the show's second season.
The fourth season of the American science fiction television series Fringe premiered on Fox on September 23, 2011 and concluded on May 11, 2012, consisting of 22 episodes. The series is produced by Bad Robot Productions in association with Warner Bros. Television. The show was officially renewed for a fourth season on March 24, 2011.
Peter's actions of using the Wave Form Device to create a bridge between the two universes have caused him to erase himself from the timeline; a new timeline, in which young Peter was not saved by September after falling through the ice of Reiden Lake in 1985 after Walter's crossing, is set in motion. Despite the absence of Peter, the bridge has created a healing effect on the parallel universe, and both Fringe teams resolve their former differences and work together on cases.
Olivia and a more sheltered Walter continue to explore Fringe events, but are aware of a memory of Peter that haunts them. Due to their actions, Peter suddenly materializes in this timeline, though his identity is not initially known nor is he trusted. However, as he spends time with the Fringe team, Olivia starts to gain memories of the original timeline, and though both are initially worried about this effect, allow it to continue on, rediscovering their romance from before. During one case, a wounded September appears to Olivia, warning her that she dies in every future that he can see, before disappearing. September later appears to Peter after he activates a strange artifact, which acted like a homing beacon to September. September explains the other Observers hid this universe from him purposely, and that this timeline is Peter's true home.
