Have done all of that and it's hopeless. Grisha only has the one sentence when I click on him and no talk options at all. The king only has the same options every time and never change I've tried several times and have even talked to Sir Patrick again and then the King. I've went to the king with the Breast Plate in inventory and wearing the Breast Plate and the King won't recognize that I have the breast plate. The King keeps saying go find the Breast plate which is probably where the hang up is but I have no idea what I have to do to trigger him ackowledging me having the armor. Maybe it's because I already had the heart and did that quest before talking to the King.

Thanks for the help but nothing seems to work.
