William Wintergreen

== Biography ==
=== Early Life ===
William “Billy” Wintergreen grew up in Oxford, England. Much of his young adult life remains unknown or classified. After briefly attending Oxford University, where he was known as a top student, he felt his true calling was in the military, and so he enrolled at the Britannia Royal Naval Academy. He was very quickly picked up to be an agent of MI-5, where he was recruited to a secret mission to provide British aid to American forces in Vietnam.
While serving in Vietnam, he made the close acquaintance of David Isherwood and Slade Wilson. The three became an inseparable trio, even when the war came to an end, where Wintergreen was the best man at Slade’s wedding. The day after the wedding, Wintergreen decided to return to his hometown.
He became a forensics professor at Oxford, his former alma mater. While working there, he developed a fancy for another professor, Anais Guillot, herself a former agent of the Maquis. She was slightly his senior, but the two had an electric affair, before Billy got a call from Slade’s wife, saying that he had fallen into a medical coma, and she desperately needed help preparing for the arrival of her child.
Wintergreen moved in with Adeline to her Gotham City home, where he helped her prepare for the baby. During this time, he and Adeline grew very close. While neither have ever confirmed an affair, it is highly suspected. Slade finally came out of his coma and returned home just in time for the birth of his first son, Grant. Billy took this as his sign to head home.
While holding late office hours, Billy was approached by a man named Wade LaFarge. Wade came to Billy with a job offer, and so the two arranged a meeting with his boss - Henri Ducard. Sitting down to dinner the next day, Ducard told Billy that his skill set made him a unique candidate for his job.
=== Inside the League of Assassins ===
The exact details of Billy’s role in the League of Assassins is unclear for this point in history, but he became a trusted advisor to both the White and Black Gloves, although apparently he was not an active assassin at any point in time. Between consultations for them, Billy went on safari expeditions with Wilson and Isherwood, and occasionally Wilson’s sons would join them.
After Slade’s anger issues started to rub off on his children, Adeline staged an intervention with Wintergreen and Isherwood, during which the couple decided to file for divorce and Billy helped Slade pack his bags. Billy scarcely saw Slade, eventually tracking him down in the midst of a drug-fueled bender in the Congo. Wanting to help his friend out of the hole, he decided to introduce him to Mr. Ducard.
Slade grew to great prominence within the League, and Billy was always there as his advisor and confidant - he was even tasked to bring his daughter Rose to the United States, where he left her on Adeline’s doorstep. He even stood by as Slade inducted his own son into the League of Assassins and later helped Slade kidnap Rose and stashed her in Billy’s basement.
Following Slade’s self-imposed exile from the League, Billy was tasked to be a field operative, although this work hardly suited him. He was very nearly caught on his first mission which forced Ra’s to reel him back into support staff territory. Wintergreen was welcomed into the fold of the Light, where he helped them coordinate between multiple supervillain agencies.
Wintergreen has also been found to be an expert manipulator and has been helping Slade work on Project Defiance to counteract the Titans. In addition, the League of Assassins also forged a law degree for him, allowing him to serve as legal counsel for any operatives when they are caught - which has worked wonders before. It is also suspected that Wintergreen has used the Lazarus Pits multiple times - due to his age but lack of aging.
