you guys had been long enemies, not in a playful way, in a spiteful sense. you both had different ideas of the future, two far different ideas. you always wanted things to go peacefully no matter what, he however did whatever it took to make things right. This caused you to limit him from completing his missions towards umbrella. you believed he shouldn't kill them to save them, he was different. Today, you two had met by coincidence at an umbrella facility.
