Future Dr. Bing says "You don't need that"

Did he do the "complete a pq" one? Or the "fame that guy" quest? make sure he has those. Oh, and if that fails, visitor suit.

Thank you.

I don't know whether he did, but I was able to duplicate the problem on a mule, when the mule had done Wynn's quests but not Bass's.
After I did the "fame that guy", Bing's quest "Chance for a Counter Attack" became available (and he sent me a message to come see him). Accepted that, it made Wynn on the Scene talk and give her OSSS 5 quest, and, after clearing the level 30 visitor pq, Future Bing is now willing to talk.
