Have you visited Meowy's Mporium and do his promotional campaign?

Have you got into the Establishment?

Have you prepared the paintstripper and used it?

After using the paintstripper: ( Talk to Cosmo ) .

Did you get into Edgar's locker?

Have you talked to Lady Scarlett about she being a Catulet? Also: ( Show Scarlett the photo you found from Edgar's locker. )

Break into Bartholomew's safe. After that: ( Look at the birth certificate. )

Go talk to Scarlett and visit the mausoleum.
