Oliver Queen's child's mother

Sandra is a woman who Oliver Queen cheated on Laurel Lance with and accidentally got pregnant.

History
When Laurel proposed apartment hunting with Oliver, Sandra was the first of two known women that he cheated on her with, the other being Sara Lance, but he accidentally got Sandra pregnant. Oliver became depressed when he learned this and told Moira Queen. Later Moira brought Sandra over to discuss the matter and made her an offer: 1 million dollars to tell Oliver that she lost the baby and another 1 million to move to Central City and never speak to him again, to which, after some uncertainty, she agreed. Later on the phone she told Oliver the "bad news", and he was relieved that he wasn't going to be a dad, unaware of the truth.
