One need not be a chamber to be haunted;

One need not be a house;

The brain has corridors surpassing

Material place. – Emily Dickinson

The Doctor knew who Rose was speaking with before she ever used Shereen's name. Whenever Rose spoke to her friend, her London accent became more prominent and her slang became nearly impenetrable.

"Oi! Shereen, I don't believe it! No! You're lyin'! He did not!" Rose spun around and walked back across the room, the phone firmly affixed to her ear. "With who? Where?" She laughed at Shereen's reply. "Bad enough the smarmy git was shaggin' the boss's wife, but in the bleedin' supply room?" Rose rolled her eyes, even as she giggled once more. "Guess security got a bit more than an eyeful, yeah?"

The Doctor smiled as he watched her pace back across the control room. She always did that when she spoke on the phone. It took her exactly 42 seconds to cross from one side to the other and she'd done it 112 times on this phone call, alone. Not that he counted, at least, not consciously. Some part of his brain just noticed that sort of thing.

Like the way her denim miniskirt molded to her body…or that glimpse of her stomach that her top exposed whenever she turned just so.

He frowned at those unruly thoughts – he certainly didn't need to be noticing those sorts of things – and turned back to the temporal condenser that didn't really need any more calibrating. He looked over to Jack, who was lounging in one of the pilot seats with his feet propped up on the edge of the console, reading a book.

Didn't they have a library for that sort of thing?

"Really? No, no – I will definitely be there. I mean, Shereen's Annual Halloween Costume Bash? That's the party of the year, yeah?"

Rose laughed. It was a laugh that vibrated through him like an electrical charge – throaty and a bit naughty. A glance at Jack verified that he'd had the same reaction. Of course, Jack would react to the wind blowing. And really, there was no reason why he needed to be draped across the equipment in here, in his control room, staring at his… The Doctor derailed that train of thought before it went any further.

"No, no. I definitely don't want you bringing out those pictures, you evil cow! I promise I'll be there! Love you, too."

Rose slipped her phone into the pocket of her skirt and turned around.

"I guess you heard that, yeah?"

Jack leaned back farther on the pilot chair so that he could look up at Rose directly.

"Those pictures?" He asked, smiling broadly.

Rose grinned and swatted at him. "Never you mind, you. Those pictures will never see the light of day."

Jack laughed. "Good thing I love costume parties, then. Especially Halloween costume parties! It's absolutely one of my favorite 21st-century holidays!"

Rose grinned, "Mine, too."

The Doctor grimaced but Rose spoke before he had a chance to utter a word.

"No." She said.

Rose walked over and tapped him on the chest with her finger.

"Before you suggest going to the Fire Moon of Quarillion Five or the Singing Glass Cliffs on Triffaxal or any other spectacular place that you've suddenly decided we have to see right now, no. Shereen is my best mate, I love her, and I am going to her party."

Rose crossed over to the door and, in a tone that brooked no argument, said. "I get that the great Time Lord might think it's silly to put on a costume and go to a party and have a pint and a laugh with a bunch of my mates. So, if you don't want to go, that's fine, but it won't kill you if we stop by home for a couple of days. Besides, I'm just about out of milk again and I want some decent chips."

With that, Rose left the control room.

Under his breath, he muttered, "Fantastic."

Jack set his book aside and took his feet down from the console.

"So," he said. "London it is, then?"

The Doctor sighed. "London it is."
