Luke almost thought it was odd how Sarah Jane could only have gotten here a day before him when so much time had passed between where they had come from but that was time travel for you, he realized. He shook his head when she mentioned a map.
He grinned when she said to dress warmly. "I'll probably need a thicker coat," he mused, taking a glace out the window. "I arrived outside. It was very cold. Now I've seen snow," he added, still smiling. "Do you want to go exploring?" Luke wasn't sure if she had anything planned but he figured he'd ask first to be polite. He'd go check out the interior of this place more thoroughly alone if she didn't want to, although he would be glad for the company.
