The Doctor linked arms with the younger man and patted his elbow, as if he himself were needing the assistance for his advanced age or they were very dear friends.
"Correct me if I'm wrong, but, I suspect you have a gift that comes with a terrible burden. It explains the eureka expression you had when I mentioned time travel.

The Doctor let the younger man lead the way, content for the moment to walk wherever Leto lead him.
