Laton did his best to ignore his sister. Like the sound of the waterfall, her questions didn't stop.
"How long will you have to travel?"
"How long will you be gone?"
"Do you really think you can win?"
""Will the king be there?"
"Will you win some money even if you lose?"
He sighed, bucled the last strap on his saddle and turned around, looking sternly at the 8-year old girl.
"Lisa. You better hope I do not lose, because it is custom that the little sister of a disgraced knight will be wed to the pigsherd."
"IS NOT"
"But you needn't fear, little sister, a pigsherd will run away when he sees your freckels and red hair."
"OH, I WILL TELL MUM YOU SAID THAT"
He laughs as his little sister runs away yelling. A cough behind him startles him.
"You shouldn't tease your sister so."
His father looks over the packhorse, and the destrier.
and walks around 'em, limping heavily and leaning on his cane. His sure hand make some minute adjustments to the tack
"Curses. I wish I could go with you. Be strong, my son. Make us proud."
Looks good.

I can't completely work up Laton's stats until the House itself is done up, but getting such ideas down can't hurt (but of course, aren't set in stone)
