Olicity

Olicity is the het ship between Oliver and Felicity from the Arrow fandom.

Canon
To begin with, Oliver and Felicity's relationship consisted of minimal conversations and Felicity's hacking skills were used to assist Oliver on various missions as "The Hood", although Felicity didn't find out his secret identity until later. Oliver found her amusing on several occasions; most notably their first meeting. They first met in I.T. Department of Queen Consolidated. Upon introducing himself, Felicity accidentally mentioned his father's death, backtracking apologetically and ending up babbling at him. This amused Oliver. To her relief, he ignored her ramblings and gave her a bullet-ridden laptop, claiming that he'd spilled a latte on it, though she clearly did not believe Oliver's cover-story.

Felicity's tech assistance aided many of Oliver and Diggle's cases and Oliver seems less troubled by putting his faith in her than many other people he comes across. When Moira unwittingly shoots her son, Oliver asks Felicity for help, risking exposure of his secret identity. Assisting Diggle, Felicity helps save Oliver's life and a new era begins of the team becoming a trio. Although Felicity has some moral quibbles with Oliver's methods, she chooses to stay with the team and help them fight for justice in Star City. In 6x10 they finally get married and raise William happily as a family.

Season One
LONE GUNMEN

Oliver heads to Queen Consolidated's tech department and finds a woman named Felicity Smoak. After some awkward back and forth, he tells her that he was having trouble with his computer, and hands it over. He says he spilled a latte on it, but she says it's probably the bullet holes. He asks her to salvage anything she can, and she gives a nod to confirm that she'll try.

After some time, she's able to get the information pulled up from it, and shows him several blue prints. When he doesn't know what some of the stuff on it is, she tells him that she didn't want to get involved in whatever family drama was going on, confusing Oliver. She explains that Walter is trying to buy the company that the blue prints show the building of, and the laptop is from one of it's employees.
