Felicity, shocked by his action, stopped him by pulling the plug.
One night, Felicity entered the CEO's office and stared at the picture of Oliver and said he was cute. 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.
Unaware that Oliver himself was hidden nearby and listening talking to herself, she later left and he smiled.. Felicity retrieved blueprints to the Exchange building, where Walter Steele would be bidding on the Unidac Industries auction.
Felicity met Oliver while working in the IT department at Queen Consolidated, when he asked her for many favors related to his vigilante activities. When she was very young, her father abandoned her and her mother.
She discovered his secret and despite some initial reservations joined his team, coining the name "Team Arrow", and after many adventures, the two fell in love. She reportedly lived in Las Vegas with her mother until she went to college.
Following the defeat of Ra's al Ghul, Felicity and Oliver left Star City to begin a new life together, but after five months returned to rejoin Team Arrow and face the threat of Damien Darhk and H. At a young age, Felicity became interested in computers, claiming to have been building them since she was 7. She had an incident with a stalker in her freshmen year.
