Is There Much Written About Lionel?

Lionel is a fascinating character to talk about I think because that's a huge book. Can you talk a little bit about some of the backstory that you came up with, how you connected some of the dots for yourself? There isn't much written about him in the books but there's plenty that was written in the script. The family had already had somebody in the family be a hand of the king. So there was a lot of history in terms of this is a guy who knows what he's talking about.
