Why was this Byron fellow getting under his skin? Maybe because he was the sort of capable, charming type that could take Rose away from the Doctor if he tried hard enough. Maybe it was because the Doctor had more than a few of Byron's poetry books, and therefore couldn't call the man anything but a genius in the literary sense.
Not as frustrating, of course, as the TARDIS was being. It kept registering a non-human lifeform within the console room. At first the Doctor figured it was reading Rose (after the Time Vortex incident, she never did show up as fully human according to the TARDIS scanners), but she'd been gone for a good fifteen minutes, now, and the scanner shouldn't have been continually reading her.
He looked up and around the console room. Nothing was there...or was it?
