And we'd love to help - however... I can't really help you unless you explain how much you already know. Do you want to leanr how to edit pages? Or do you already know the basics and wonder what you could edit?
Do you have any source for Patricia? She's not named in #84, and only called Tricia (Trish for short) in John Constantine - Hellblazer: All His Engines. Fennel even writes her name across his chest - Tricia Chandler, not Patricia Chandler.
