The Doctor lingered in the console room when Donna and Rose first went inside. No one remarked upon it, but the two women did share a confused look. But he’d said he would be out in a few minutes, so they left him to it and went to say hello to Sylvia and Wilf.
“Mum, Gramps - this is Rose.”
“Lovely to meet you both,” Rose said politely, shaking Wilf’s hand. She felt Sylvia look her up and down, but a smile soon came to her face, so she guessed that she had been met with approval.
