Ah favourite character to write, ignoring the ones taken I would have been thinking Cassidy.
Don't know why but getting inside his head would likely be hilarious or terrifying.
Sure no real action yet but his presence sets a scene.
Spoiler
When I was writing that Dark Ages game that fell through due to my inability to maintain it, I had a character that I likely thinking about and wondering about the PC's reactions when his actions became known: namely the prince and the children.
I even had a picture to introduce him and them when the time was right.
Spoiled to allow for the surprise.
