Storm

The Remy who joined the Time Broker's Weapon X team had been married to the Storm of his reality before she died and he became unhinged from time. There was also a Storm that joined the Weapon X team from another reality, who had also been romantically involved with her Remy, and the two of them got close before she was killed and replaced by Hyperion. She died in Remy's arms. Finally there was the Storm of one of the realities that the Weapon X team was sent to, who had loved and lost her own Remy and didn't mind that the Weapon X Remy wasn't her own. When Hyperion began to follow the Time Broker's orders, which were to kill the last remaining mutants on that Earth, she begged Remy to kill her quickly and cleanly so she didn't have to suffer. He obliged and stabbed her, where she died in his arms.
