The streets swarm with nagri, skeludancers, dabby girls and blufers. Carnival on Ordovicco: by law, everyone must be costumed and masked.

He sighs inside his nagr hood. He didn't want to visit Ordovicco, but Jack and Rose pleaded, and he coudn't find it in his hearts to refuse.

A blufer escorts a dabby girl whose yellow feathers match her hair. They rotate slowly, searching the crowds.

He smiles. They haven't seen his costume, and many nagri wear identical robes.

"Doctor!"

The dabby and the blufer hug him.

He shouldn't be surprised. They've always been able to see through his masks.
