New Queen Needed?
Sounds like C1 needs a new queen. Some would say to leave them alone and they will raise their own queen based on the fact that they have capped queen cells. Apparently your bees are trying to make a new queen, but your supersedure cells may not produce as good a queen as you want. I would think you should see evidence of the queen's presence by now...either by physically seeing the queen or eggs or larvae, etc. Some might suggest that you destroy the queen cells and order a new queen asap and introduce her. Good luck with whatever you decide. Let us know how it goes!
