"Huh? Oh!" Oliver grinned, amused by her amazement. He was rather proud of those pockets. "Aren't they? The Doctor got them made for me. You wouldn't believe how much stuff you can put in there!" He folded up the remaining bit of trousers and, eyeing his boots, decided he could probably get them in there. He proceeded to do a bit of old-fashioned stuffing. There. Now he wouldn't have to worry about his clothing at all!

He took the badge eagerly, looking it over with a very wide grin before he nodded and offered it back to her. "Cheers." He couldn't resist adding: "This is so cool, Christine! Does the badge just track people, or does it do anything else?"
