Sarah Jane's smile widened as Shannon introduced herself and seemed to recognize her. She remembered the name from the journals as well. "Yes, the Doctor's friend. I'm glad to meet you in person, and to see you're still in one piece." That strange entry about getting rid of a clone version of Shannon was still troubling. "The Doctor said I could stay here. I do hope that's all right." She could tell that Shannon was a bit unnerved by her use of the word 'home.' It wouldn't surprise her if the Doctor had neglected to mention a new arrival to the other residents of the museum - he'd just assume everyone would be fine with it. She might remind him later about such things, if she thought of it. She didn't want to startle people or make them uncomfortable. Goodness knew this place could do a good enough job of it on its own.
She turned to the other woman as she introduced herself. "Pleased to meet you, Ripley," she said, offering another bright smile. "I only arrived here two days ago myself, so I'm still finding my way round."
