Ryan was struck silent and the Doctor just smiled and sipped her tea, playing coy. It would only last so long, of course, as Graham was flustered. "Wife? I thought she- I mean. Not that I'm gonna judge, just that-"
"Thought what?" The Doctor was on her feet, coming over and putting an arm around River's shoulders. "Course I'm married! Been married a few times, actually- once to Queen Elizabeth. The first one, not the second one. Or the others." She made sure to correct that then smiled at River.
"But River's different. Her parents were my companions, actually. Sounds weird when I put it like that, doesn't it?" She looked again at River, making a face then removing her arm.
"I have questions," Ryan started up.
"Of course you do! But we can ask those in the TARDIS- I had some readings I need to follow and we're late."
Not that time really mattered. The Doctor was just looking for an excuse to get going.
