William didn't flinch or step away when Daenerys reached out a hand to touch him. It was as if she was reconciling the fact that he wasn't the man that she was looking for. He could see the sadness in her eyes -- whoever Drogo was she must have loved him very much. "I'm sorry that I'm not who you'd hoped," he rumbled.
He'd heard it through the grapevine that a Queen by the name of Danerys had arrived (little Dany Hanson would likely be thrilled by the news), but no one had explained her presence -- her poise, her bearing. He couldn't help it but feel awed by her.
He wasn't really sure of the proper etiquette for meeting a Queen, so he did what felt natural and gave a small nod of his head. "It is my honor to meet you, Queen Daenerys."
