The leis as a device? [He raises an eyebrow and casts a glance down towards the garish thing around his neck.] That's a thought. Has anyone else explored it?

[He would have but with a fritzing Sonic Screwdriver and no other working equipment on board it's a tad more difficult than it normally would be for him. The Doctor seems to ponder it for a minute before tuning back into what Clara is explaining and she'd be able to tell that he's got that familiar, excited sparkle in them.]

Fascinating. It's not entirely out of the realm of possibility. Maybe this place is just a pocket universe functioning on its own. Anyone from your Earth? [Honestly, save for the sick micro management element to this place, the Doctor is having a pretty good time with that prospect in mind.]
