Early Life

Thea Queen (Arrowverse) 003

Thea during her younger years

Originally believed to be the daughter of Robert Queen and Moira Queen, Thea was the younger sister of Oliver Queen until he supposedly died with their father on the Queen's Gambit.[1] In reality, her brother survived and lived the next 5 years on the island of Lian Yu, during this time Thea developed a rebellious attitude and a drug habit.[2] Although she began to become clean after criminal charges are brought against her for driving while under the influence.[3]

During this time she also met a man named Roy Harper and later began a relationship with him.[4][5] After the collapse of the Glades and Oliver's return to the island, Thea took over Oliver's club. However, her relationship with her family and Roy swiftly began to break down due to Roy experiencing psychological issues after he was dosed with mirakuru- a strength-enhancing drug that also compromised his capacity for rational thought. Thea later learned from Slade Wilson that Malcolm Merlyn was her biological father and nobody else had told her about this.[6] She was subsequently contacted by the resurrected Malcolm Merlyn, and accepted his offer to accompany him for training.[7]

Becoming Speedy

While training with Malcolm, he drugged Thea so that she would return to Starling and murder Sara Lance on his orders, provoking a chain of events that would force Oliver to fight Ra's al Ghul to protect Malcolm.
