1. The WG probably doesn't know.
2. Don't think Vegapunk has control over Stussy. She's just a normal clone with free will unlike Seraphims.
3. I don't think so. Lucci is still the leader of the CP0 group.
4. She is clone number #1, so there should be at least 1 more clone.
5. Yas, mommy!
Bonus question, would you let Stussy sucked you?
Yes yes yes.
