"I've got to meet this Nardole guy. He sounds like my kind of people," he joked. He nearly burst out laughing when she referred to the Doctor as 'ears'. "The first time I met him, I called him Mister Spock because of a comment Rose had made. I didn't find out until later that it was a tv show character. Of course, I also teased him and said he was dressed like a U-Boat captain. Ignore the cranky bit though... he pulls that with everyone."
When it looked like Bill might be losing herself to her thoughts again, Jack was tempted to poke her again. But her next comment... oh yeah, she was definitely Companion material and had hit the nail on the head. He smiled and nodded in agreement. "Exactly. We bring out the best in each other and unfortunately, sometime the worst. But that's family... right?"
