Chase is a minor antagonist in season 3 of the TV show Arrow. He is a DJ at the nightclub Verdant and a lover of Thea Queen. He is also secretly a member of the League of Assassins.
During auditions for a new DJ at Verdant, Chase arrived claiming he was good enough to be the DJ and the others could leave. Thea told him that if he claimed to be that good, he should just audition as everyone else. As Chase said he doesn't audition, he left. During opening night, Chase dropped by to watch the "train wreck". With no other option, Chase was hired on the spot and finally brought life to the club. After the club closed for the night, Chase shared a kiss with Thea and took that as payment for the night. He later called Thea, thinking that their kiss had meant something, but Thea shot him down.
Chase later dropped by Verdant and encountered Thea, claiming he wanted to stash his possessions at the club due to Brick threatening the Glades. The next day, when Thea told him she wasn't leaving, Chase calls Sarab to confirm that Malcolm Merlyn wasn't leaving Starling City, revealing himself as a member of the League of Assassins.
Soon afterwards, Chase bumped into Thea outside Verdant. The two kissed and went back to Thea's apartment. After they spent the evening together, Chase tried to poison her with cyanide in her red wine. Thea smelled the scent and revealed her father taught her red wine was effective in covering the scent of poison. Thea then attempted to attack him with a knife. Chase and Thea fought and Chase ended up overpowering her. Chase revealed himself as a member of the League to her, however he was attacked by Arsenal. After a short fight, Chase knocked Arsenal down, but got shot in the back by Malcolm Merlyn. Chase then drank cyanide and died.
Chase was seemingly an overconfident and fun loving guy who felt attracted to Thea. However, he was later revealed to be a highly committed assassin sent by Ra's al Ghul to spy on Thea and kill her. He was able to hide his true intentions from her and tried to kill her just moments after they had slept with each other. He was fully committed to the League as he quickly took his own life when Malcolm had him cornered. Because he was growing fond of Thea, he decided to try and poison her instead of an otherwise gruesome death, as is the League's way.
