They are both attacked but Malcolm is able to subdue them. Thea grabs a gun off the assailants and shoots Malcolm as he tries to reason with her.

Character traitsEdit

Thea can be reckless, impulsive, and immature, but she has a good heart and always tries to do the right thing, and looks up to her older half-brother Oliver. When she meets Roy Harper, the young criminal, she quickly forms a strong romantic attraction, and she is shown to be extremely devoted to him, repeatedly bailing him out of jail. After Roy is saved by The Arrow, Thea goes along with him to meet the man who saved his life. This shows that Thea, while young, reckless, and impulsive, has a strong sense of loyalty and camaraderie for those she loves.

After working with Laurel, her partying and drug abusing days seem to be exchanged for a more dutiful and emotionally responsible personality. In Season 2, though Thea was originally opposed to being a vigilante like the Arrow she eventually warmed up to it when Roy saved Sin, though Thea still tried to be involved as possible. When Roy is injected with Mirakuru, which Thea isn't told about and becomes more aggressive, Thea begins to feel pushed away as Roy doesn't talk about it. When Roy breaks up with her she becomes extremely depressed. Furthermore when Thea finds out Malcolm Merlyn is her biological father, she becomes angry towards Oliver and her mother Moira, for keeping the secret from her. She can tell when someone is lying to her and hates secrets, particularly when she knows her family and friends have them and refuse to admit it.

In Season 1, Thea was a reckless and immature drug addict, with temper issues, but when she gets arrested for taking the drug "Vertigo" is sentenced to community service with Laurel Lance and starts a relationship with a street criminal, Roy Harper - her time spent at CNRI made her more responsible, and she genuinely falls in love with Roy, eventually managing to persuade him to a life away from crime.

In Season 2, she owns Oliver's club Verdant , and is in a stable relationship with Roy but is irritated by his need to be a vigilante also like the Arrow. Increasingly it is revealed multiple secrets have been kept from Thea, from almost everyone she loves and trusts the most, beginning when Slade Wilson abducts and tells her that Malcolm is her father, and that Oliver and Moira knew. Also, Thea breaks up with Roy when he cheats on her (though it was to keep her safe from his Mirakuru abilities). These events left her estranged from her half-brother and mother until recent evens which saw her mother killed by Slade.

When Starling City is attacked by Slade's Mirakuru army, Malcolm returns to save his daughter. Originally wanting nothing to do with him, Thea reaches her breaking point when, in a final attempt to reconcile with Roy, she discovers he is secretly the Arrow's sidekick, which he kept from her all along. After all these lies uncovered, she decides to start her life over. Leaving a goodbye note to Roy, Thea decides to go with her father and leaves Starling City and her family behind, intending never to come back.
