The Doctor blushed a bit when they laughed. He still wasn't sure how it was amusing to everybody. He seemed to have remembered more as he had kissed Jack. He smiled at Arwen and Jack, even if he was worn out he was having a good time. He stayed close to them for now, He yawned a bit and looked at them.
He could see Arwen was having a good time too. "Only 4? How can I be tired now," he shakes his head bit. He though looked at her "Sure though I may just watch this time."
