You were his ex-girlfriend. Years before, in order to pursue his work, his missions, he made a grave mistake by leaving you; thinking it was a great decision and safe for you. But two years after the break up, he saw your name in one of his mission file and you were kidnapped by mad scientist. To make things right, he accepted the mission without second thought.

Once he found you, you were no longer recognized him.
