Winn Schott

Winslow "Winn" Schott Jr. is a programmer at CatCo Worldwide Media and Kara's best friend.

Early life
Winn was close to his father, Winslow Schott Sr., and the two would go to the latter's workshop, and build toys often. After Chester Dunholtz stole Winslow Schott Sr.'s toy designs, Schott sent a teddy bear with a bomb in it to Dunholtz, killing six people with it. At 11 years old, Winn had to watch his father dragged off to prison. . At some point after this, his mother ran off. Later in his life, Winn became employed at CatCo, and became the best friend of Kara Danvers. He believed in the existence of aliens other than Superman, citing an armored car robber who reportedly had horns, and maintained a web site documenting alien sightings. He has feelings for Kara and has unsuccessfully attempted on several occasions to ask her out or tell her about them. In many ways an archetypal IT geek, Winn nevertheless doesn't believe that everything in life can be modeled by algorithms.

Assisting Supergirl
After the rescue of Flight 237, Kara confides in Winn that she was the woman who saved the plane. Winn was skeptical until Kara showed him her powers, and then enthusiastically assisted her, helping to design her costume and alerting her to several crimes and disasters. He was also eager to hear about her first fight with an alien, Vartox.

A week later, Winn alerted Kara of a fire raging at the National City Port, and offered her comfort about the mistakes she made in her early superhero career. Winn tried to downplay the importance of Maxwell Lord's public criticism of Supergirl, despite Lord being Winn's personal hero. Winn was surprised when Kara revealed that James Olsen also knew her secret identity, but accepted that she'd need both of their help to prove to everyone that she knew what she was doing. He worked with James to advise Kara while she responding to a number of lesser emergencies from Kara's apartment, for which Kara was thankful.

Winn later converted an abandoned office in the CatCo building into a secret base of operations, showing it to Kara and James. They first used it to discuss their plans to defeat Reactron. When James carelessly refers "Clark", Winn quickly works out that Clark Kent is Superman. That night at Cat's launch party, Winn covered for Kara's late arrival, asking her to dance in lieu of any reward - though James cuts in when he arrives. During Reactron's attack Winn was almost crushed by a falling support beam, but was saved by Kara.

At Thanksgiving, Winn reveals he has no plans, and cautiously accepts Kara's invitation to share the holiday with her family, meeting Eliza Danvers for the first time. He leaves after Alex and Eliza have a fight over Alex's work with the D.E.O. Kara later apologizes for the family drama by giving Winn some leftovers, and he reveals that his lack of plans is because his father is deservedly in prison. He kisses Kara on the cheek, but they are interrupted by the arrival of James and Lucy.

When Cat receives an award and Kara offers to watch her son Carter so she can attend the ceremony, Winn is roped into taking after him when she has to leave the office as Supergirl to deal with a number of suspicious attacks on Lord Technologies. Winn unexpectedly gets along very well with Carter, finding they have much in common, but is distraught when Carter sneaks off to the launch of Maxwell Lord's new superfast train in the hopes of meeting Supergirl. He calls Kara and she trusts him over D.E.O. reports of a bomb at the airport, heading to the train and saving everyone aboard except the bomber. Winn checks on hospital records for Kara, revealing that the bomber's sick daughter was having all of her medical bills paid by Lord, leading Kara to confront him over his involvement in the attacks.

Growing more suspicious of Hank, Alex tells Winn that her father Jeremiah was killed while on an assignment working for the D.E.O., and asks him to hack into their servers to see what he can find out. Winn reluctantly agrees. He also joins James in advising Kara that she doesn't have to fight the Red Tornado, but she wants to prove to General Lane she and her cousin can be trusted. He is less than thrilled when Kara reveals James is bringing Lucy to games night; their closeness in a game of Taboo makes Kara even more jealous of Lucy's relationship with James. Later Winn meets with Alex and Kara to reveal that Jeremiah was one of two agents who went missing, presumed dead, while tracking down an alien in South America. The other agent later reappeared - it was Hank, who has been tampering with Jeremiah's files every since.

When an earthquake hits while Kara is without her powers, Winn helps restore telecommunications to the CatCo offices, earning the notice of Cat, who asks him to hook up a live feed so she can send a positive message of hope to the city. He also walks in on James and Kara sharing a hug and assumes it is romantic, making him even more jealous of James and disappointed in Kara. He criticises her, reminding her that James has a girlfriend and claiming that when her powers return she won't ever have a normal life or relationship. He and James are forced to work together the next week when they and Kara are tasked by Cat with the delicate task of damage control when her email is hacked and made public. Though initially it seems there's nothing too scandalous, Winn eventually finds a series of mysterious payments to Adam Foster, a young man in Opal City. Before this potentially damaging revelation is made public, with the help of James and Lucy, Winn figures out a way to get legally admissible evidence proving the leak came from the Chair of the CatCo board. After spending time together with both of them, James recognizes Winn's feelings for Kara and tells him to take a risk and tell her how he feels.
