Lucas "Lindsay" Stanton is the identical twin brother of Logan Stanton.
Background[]
After Lucas underwent a botched circumcision from a laser, the boys' parents, unbeknownst to either of the twins, had Luke undergo surgeries to help him switch genders to become Lindsay Stanton. A sex therapist named Dr. Preston Blair experimented on the twins to try and make them take on the gender identities assigned to them in a dichotomy they never consented to. Even the parents were so on board to the point of regularly feeding Lindsay estrogen and losing it when Lindsay was in a relationship with a cisgender girl. The twins still kept a close yet tense bond, even to developing their own twin language, which is common in identical and fraternal siblings.
Identity[]
Lindsay was orally raped by a member, Luis Vega, of the Stone Cold Assassins, a gang that primarily worked in the Upper East Side and was notoriously murderous and sexually violent. This was when Lindsay wanted to be a street artist like Logan was before he was caught. When Lindsay bit the gangbanger's penis, the thug was killed from a fall off a rooftop from stumbling back in pain. When DNA evidence showed that the sex chromosome was XY, attention was drawn to Logan, even though Lindsay provided Logan's alibi when she was first introduced. When Logan was set off by Dr. Rebecca Hendrix due to not wanting more therapy, Lindsay defended him by swinging a candlestick at Stabler's back, leading Benson to restrain her too ad the twins being admitted to an emergency psych stay. It is then revealed that Lindsay was in fact the one on the roof, and not Logan, when the twins' birth records were revealed.
When the truth of the murder came out with Lindsay's real gender and her birth name, Lindsay was devastated when her parents and Blair finally admitted it to her directly, at Dr. Hendrix's and Novak's coercion. Logan then came forward and reported the doctor's experiments on the twins were sexual abuse, forcing them to act out sexual activity with each other and showing them nude photos to reinforce the abuse, all for Blair's thesis being "proven". The twins later conspired so that one murdered Blair at the office while the other was at the movies for an alibi. Even with spit on the doctor's face, without pinpointing which brother was responsible, Logan or Luke, the legal system had no laws to charge them by, leading to their release from a failed case of conspiracy of murder.
