Wesker is kind of hinting at the queen;):D
At the very beginning of the story, the queen is sitting in the castle and is terribly annoying the king (or is it a mask?).
Therefore:
The Queen is -
not a Witch (a mechanic specialist in the squad)
not Neira, Drakkosha, and Vervolka (wandering through the forests - acting as partisans?)
