Arrow Season 4: 10 Characters That Absolutely Cannot Die
2. Thea Queen
Who She Is: Thea Queen is the beloved baby sister of Oliver Queen. Bratty and entitled for the first half of the first season, Thea has since evolved into a strong young woman. Despite being drugged by her biological father and used as a puppet to commit terrible deeds, she has chosen to use the skills that he instilled in her to fight for good as Speedy in Starling City.
Why She Cannot Die: For one thing, she pretty much already died. Although she was never flung onto a dumpster and shoved into cold storage a la Sara, her confrontation with Ra’s al Ghul would have killed her without the assistance of a dip in the Lazarus Pit. Arrow should at least wait a bit before throwing her into mortal peril once more.
The main reason why Thea cannot die, however, is that she is Oliver’s last untainted connection to the good that was in him before the island. He’s lost Tommy and his parents, and none of the Lance family should have much good to say about him from before Lian Yu, but Thea is the connective thread proving that Oliver has always had the good heart beneath all of the moral failures and terrible hair.
Oliver losing Thea would be Oliver losing the good of who he was before his crucible.
