It was probably a given that the Clerks 2
regulars would be back for the new film, even Rosario. She had so much rollicking fun making the last movie and enjoyed her castmates so much that I would have been seriously disappointed had she said no.
I hope Kevin dips into the Askewniverse for supporting and cameo characters. Willam Black. Brodie Bruce. T.S. Quint. Alyssa Jones. Those kinds of people. We haven't seen some of them in close to 20 years. This film would be the perfect opportunity to bring at least a couple of them back for one last hurrah just in case Kevin doesn't make any more Askewniverse films after this one.
Besides, Randal and Brodie are cousins you know. The late, deeply perverted Cousin Walter is a relative of both.
