Not troublesome at all (otherwise I wouldn't respond).
Yes, Tricky Ed goes stone-faced & blank once you've had the second jar of honey from him. At least as a store assistant - or is he the owner? - he doesn't want to know Kate after that, for retail purposes. (However ..., if you get Kate to go computer dating, or clubbing, visiting hotels, etc., Edwin is definitely interested in Kate on that sort of basis.)
So I can only think there's some other step along the way you've missed. I'm not sure what that may be.
Do you recognize all of these, for example?:
> Kate's solo meditations in the gym?
> Kate dreaming of Eva at highest level ("Insexsity, Level 7") in Kate's apartment, including taking the big hand in the swirling background? (after the second honey)
> All Victor's assignments for Kate completed, including those after 9 p.m.?
> Strange events on the floor in Ed's supermarket?
> All the back alley battles with one or two opponents, incl. Kate losing?
> Full sex with Don in his room?
It's bad to get "stuck" (ask Kate about that, and you'll think you're lucky, but ...). I hope someone can debug your progress!
