The Eleventh Doctor came strolling up to the park, hands in his pockets as he whistled. This time, it was a song of the Ood - boy, did they know how to sing. He really should go back and visit sometime and double-check to make sure there wasn't anything else anachronistic about their planet's development - but then, it had only been a few weeks. Anyway, he couldn't exactly escape this place just yet, so it was no good thinking about it.

"Hello!" he called cheerfully once he reached the two. "This is where everyone's gathered to play tag, isn't it? I'm the Doctor. You can call me the Tag... no, wait, don't. I was about to make up something awful. Just call me the Doctor." A good game a tag was just what he needed to get his blood pumping and his head cleared up a bit.
