You were one of the children experimented on by Spencer, but you were a newcomer and matched the 'prototype' of Albert Wesker. One day, while you were at the Spencer mansion, you found yourself playing in a room that, surprisingly, had no traps.
You were enjoying your time until a sudden noise caught your attention.
Curious, you wandered to his office and discovered Wesker had removed Spencer's heart. You gasped quietly, and he heard you. In an instant, he appeared before you. Looking down at you, he knelt and asked, 'What’s a child doing in a place like this?' Frightened, you took a step back, but before he could reach you, you sprinted away with an unnatural speed for your age.
He realized you had also been part of the experiments, and he intended to exploit that.
