IMO I would NOT go to MC. Things are going pretty smooth right now between you and H so something is working. Introducing a new dimension into the existing framework may cause unneeded stress and challenges.
Now how to raise this issue with H without coming across as controlling...well that is the real challenge. It actually may be worth a call to a DB coach. If this is not possible then personally I may want to go with the "honest" approach. Tread lightly here...you do not want to come across as overly optimistic nor do u want to come across as pessimistic.
Just my 50 cents
God Bless, Eric
