A decade earlier, The Vigilante stepped out of a small shed onto the street, a large bag slung across his back. Rose came out after him. "So, we're just going to blow them up as soon as they hit the ground."
"Nope. I'm going to blow them up before they even get close to the ground."
"Oh." Rose leaned against the side of the TARDIS and pursed her lips. The Vigilante glanced at her as he set up a tripod. "What?"
"Well, it's just that... The Doctor would give them a chance to surrender before he did anything like that."
"Yes, he would. And that's why he's skulking around in the TARDIS, and I'm about to pull the trigger out here." On top of the tripod, he placed a rubber duck with a tiny antenna sticking out of the top of its head. Rose began to laugh hysterically. The Vigilante looked at her, concerned. "What? What'd I do?"
"That's going to blow up the ship?"
"Yep."
"You do realise it's a rubber duck?"
"Ah, but that's where you're wrong. This little fellow is actually a remote guided missile with a fourteen-megaton ordinance of explosives jammed inside it." The Vigilante twanged the little antenna with his finger. "I call it the Ducky of Deadly Blow-it-up-edness!"
