Luke nodded as he listened to Sarah Jane. "Alright. I promise I won't mention anything that hasn't happened yet, for the Doctor or for you. Do you remember the exact day it was when you were brought here?" It was times like this he was glad he had an eidetic memory. Once Sarah Jane told him the date, it would be easy to split the time between what she did know and didn't.
"I hope we remember this place. I've already seen lots of things that I've never seen or heard about back home, even from Mr. Smith." He couldn't help but let excitement leak into his tone as he reached out and took one of the offered biscuits. "Thank you," he said politely. "And I promise I won't go anywhere without telling you first." Luke remembered how frantic Clyde's mother had been when he'd gone off with his father. He didn't want to make Sarah Jane worry about him like that.
