So, I want to start this off by apologizing. I am fairly new to this site and never got around to announcing what happened.
It was just an ordinary signing, but one kid's question, to me, changed some theories that I have heard a lot of.
"Is it possible for two Shards to *cough* 'procreate' and create a new Shard?
Brandon: "Ummmm, thank you for keeping that PG for one. I think that I will have to RAFO that *audience gasp and 'ooh' because it was the first RAFO of the night* but until then, no. It is not possible for two Shards to, as you say, 'procreate', to create a new, baby Shard."
So there you have it, I thought this was an huge discovery because it may change what we know about the Child (see Oathbringer letter #2).
