I confidently predict:
- Miles is now a divorced alcoholic and Conservative MP for Frottwich on the Knold.
- Milly died some time ago in a bizarre bathroom drowning accident.
- Egg still in mourning for Milly and hasn't come out from under his duvet cover in 8 years.
- Ferdie and Warren run a "modelling agency" (male brothel).
- Evil Rachel is a New Labour spin doctor.
- Anna is an international ninja assassin.
Actually, I much more confidently predict that half the cast won't come back for it and it probably won't be very good at all. Still there's curiosity value there....
