After defeating the undead army, they finally arrived at the last sealed room; Dio muttered a magical incantation, and a glowing door appeared.
"Ladies first," Dio said.
"Yeah, yeah, you have no idea what's behind that door, but you can bet it isn't pleasant," Flagon muttered.
"That's what I brought a dragon along for. Do you mind? Time's a wasting."
Flagon snorted, heated up just in case, and opened the door. She was immediately greeted by hordes of ravenous hell-bats, which she wasted no time flaming until well done. She peeked into the room, and seeing nothing of particular interest, started munching on braised bat. Dio pushed past her into the room.
"Want some of this? They're pretty good," she said, munching on another dozen.
"No thanks," Dio replied, intent on searching the room. There, on a table, was the object they had come to retrieve.
"What is it?" Flagon said between munching.
"A wafer-thin after-dinner mint," Dio replied.
Flagon shrugged. They had defeated greater enemies to retrieve even less likely objects before. "There wouldn't happen to be a second one?" the dragon said, belching a tongue of flame.
"No, and we will need this one," Dio said.
"I know better than to ask for what, where, and when," Flagon said from vast experience. "But you know, as often as you use these items, you seem to be collecting a whole lot more than you use. Saving up for a yard sale?"
"Time is long, and we have just started down the path," Dio said, then got the strangest look on his face as he tried to stuff the mint into his hyper-pocket.
"Problems boss?" Flagon said, as she picked up a discarded lance for use as a tooth pick.
"I can't fit the mint into my pocket."
"I'm sorry, I don't understand. It's a wafer-thin mint. What do you mean it doesn't fit?"
"My pocket is full."
"Wait a second, isn't that pocket an opening to null space?"
"Yeah."
"Are you telling me you managed to fill null space?"
"It appears that way."
"I thought null space didn't have any dimensions..."
"It doesn't that I know about."
"That's a heck of a lot of stuff then," Flagon concluded, impressed. "So what do you plan to do about it?"
"I think it's time we did some spring cleaning."
"I agree with all you just said aside from the 'we' part," Flagon said, buffing her talons.
"Right. Change into human form would you. It saves on space."
"I hardly see where that would make a difference. You can't even fit that mint in there."
"Yeah, but I set it so it would register full when where was only enough space for the two of us."
"Then it should hold you and the mint nicely," Flagon said, just before she was sucked into null space behind Dio.
"Great, just great," Flagon remarked, as she moved a kitchen sink away from her face. "At least we got that old line out of the way early. Just look at all this stuff!"
"True," Dio admitted. "I hardly know where to begin."
"I would say this pair of old gym socks would be a start, unless you are saving them for the Laundromat at the end of the Universe."
"The problem is I still don't know if there is anything here I can throw out."
"Dio, there is a technical manual for DOS 3.3 here. Whatever are you going to need that for?"
"It's the native operating system for the Infinite Improbability Engine."
"Are you sure? I mean what are the chances of that... Oh, never mind. Ah here's something. A copy of 'Proofreading for Dummies'. Hmmm... it doesn't look like it has ever been opened."
"Do you mind?" Dio said, quickly grabbing it from her. "Now let's get serious here."
"That would be a change," observed Flagon. "OK, let me see if I understand the problem. Since you don't know which alternate probability path time is going to take at any point in the future, you don't know what items might prove to be vital to solving a situation. Is that about right?"
"Pretty much."
"OK, so what about choices the universe has already made. Aren't those probability paths dead ends now?"
Dio stopped what he was doing, which was sorting aimlessly through a stack of 45 RPM records, and got a deer-in-the-headlights look. "Of course! That's it!"
"What, the answer to Life, the Universe, and Everything," Flagon asked, looking at the record Dio was currently holding. "I hardly believe the Monkey's 'I'm a Believer' is that important."
"What, er, no," Dio said, dropping the record, "what you said about probability paths in the past being dead ends. Of course that's the answer. And it let's me get rid of one very big item at least."
"And that would be?" Flagon asked, curious.
"A galaxy I stowed away."
"That wouldn't be a Ford Galaxy would it? That would be just Perfect."
Dio winced. He probably wasn't the only one. "Flagon, can we stick to one bad pun at a time?"
"I suppose we could, but there is always word count to consider."
Dio ignored her, and started separating out a massive pile of stuff.
Flagon looked over his shoulder. "A lime-green leisure suit? Let's not get rash here."
"Believe me, we are well past that dead-end path. Much to my relief I might add"
"Probably everybody's. So what now?"
"Now I poof it all out of here," Dio said, striking a wizardly pose. There was a flash of light, a peal of thunder, and... nothing. Dio scratched his head. "It was supposed to have all gone away," he said.
"Perhaps we need dramatic lighting."
"Perhaps we need more space," Dio said, thinking. "I think we have one item too many in here."
"Only one?" Flagon said. "Seems to me we have a whole null space full of that." Just then she noticed a small object floating by. "Hey, it's the after-dinner mint," she said grabbing it, and popping it in her mouth.
"FLAGON WAIT!", Dio shouted, and there was a mighty whoosh as objects started exiting null space.
They soon found themselves back in the sealed room amid a pile of rubble, There was now a hole in the top of the mountain containing the room roughly the size an escaping galaxy would make, which is to say quite large.
Flagon stood up and brushed herself off. "Well that's something you don't see everyday."
Dio stood unsteadily. "Flagon, I don't suppose you would mind warning me next time you do something like that."
"Not at all, what did I do?"
"You... oh never mind. Let's go."
"Oh, here is something else I found," Flagon said, offering Dio an item. "It's a towel. I understand you should never go anywhere without one."
