Leto nodded to all of the descriptors she'd given the Doctor, though he hesitated at the 'Alien Time Lord with two hearts' bit. "Not sure about that -- but he did have a bow tie."
Leto's own sense of fashion was still routed deeply in Arrakis -- but that sort of clothing was impossible to find here in the City, and even if it could be found, it would be dreadfully out of place. Leto knew enough by now about the fashion expected in this world to know that what the Doctor wore was not in fashion. Yet, The Doctor dressed as if he were comfortable being out of place. Good for him, Leto thought.
As for Leto, something of his aristocratic blood had stayed with him, enough to make him want to be careful about how he presented himself - if only just enough to keep him from seeming wholly strange. He was that, though. Strange.
"In the pond?" Leto asked, his eyebrows shooting up. Perhaps he wasn't as strange as he'd believed! "Well, all right, then. Would you like me to manage the invitations?"
In truth, Leto expected to manage most of it. Oswin didn't have hands.
