Bronze is a very pleasant break from the high drama of the mainline story. As a matter of fact each of the interludes have provided a nice respite from the drama of the story. They also provide that little bit of extra color and background that adds to the overall enjoyment of the story. That being so, I wouldn't expect them to advance the story, that is for the main story. They might add some answers or other information that would be awkward to have in the story. Then again, maybe not. No matter, I enjoy them for what they are.
Anyway... It was interesting to see a little of how the Kalorians faired in Taldor Valen in the early years after Angels Falls through the eyes of Larrus. How he really took to heart what his friend, The Prince, told him, "Friends help friends."
Yes, Charlie and Giovanni have already mated. That they had mated was the cause of all the anguish when Jamie told them that they had to separate to keep them safe. Even though it has never been said outright, I believe that just as Nic was created to be Jamie's mate from the DNA of Agramos, so was Giovanni created to be Charlie's mate from the same DNA.
Remember, iron and bronze are baser medals when compared to silver and gold and if any answers are to be forthcoming in an interlude it would seem to me that silver or gold would be the proper vehicle. But, if not, they will still provide a nice pause before we return to the drama.
Take care
