There was a strange noise like the wheezing of gears, groaning with a heavy load.

"What's that sound?" Gwen asked. They were in the pub, celebrating a quiet day. Jack cocked his head, then his entire face lit up with a smile.

"I've got to go!" He chugged his beer, and sprinted out the door, snagging his coat along the way. Gwen raised her brows and exchanged a surprised look with Ianto.

Ianto stayed with the drinks, and Gwen followed Jack out the door, just seconds later. The street was completely empty. There were leaves dancing in the air, as if they'd been disturbed, but no wind. Gwen blinked, and went back inside. He was a mad one, that Jack Harkness.
