Taiana

Taiana was a prisoner on Lian Yu and a former dive instructor.

Working as a dive instructor
While working a dive instructor on a yacht, they were hijacked. Everyone was killed but Taiana and her brother. They were then brought to Lian Yu to work for Baron Reiter.

Prisoner on Lian Yu
While on Lian Yu, Taiana and several others were forced to harvest heroin and cocoa leaves to produce slam. After a slam harvester passed out, she aided him and requested he should be rested and given water. She was denied and was demanded she get back to work by Oliver Queen.

Eventually, Taiana had enough and she and another worker worked together to steal some slam. When Conklin and Oliver Queen began to extract who stole the slam for other workers, Taiana came clean. Before Conklin could kill Taiana, Oliver insisted she be brought where her body couldn't be found. When Oliver escorted her, he separated their distance from a landmine which killed a mercenary. Taiana was told where she could find clean drinking water and edible plants. When she noted that Oliver wasn't like the others, Oliver told her he would need her to do something. Her death was then faked so the men would stop looking for her. Later, Conklin came by to check if she really was dead. Once Conklin left, her consciousness was regained by Oliver.

Days later, Taiana was visited by Oliver. She was asked if Reiter seemed interested in anything besides the drugs. Taiana told him he liked taking people away from their families. When asked if he had done anything mythical or magical, she told Oliver that he had claimed to have blessed some of the prisoners.

When Oliver returned, she was told that her brother was killed because of Conklin. Taiana told Oliver she was going to kill Conklin but Oliver told her Conklin is only a pawn. Taiana was then shown a map of Lian Yu and told it could lead to what Reiter was looking for.
