Based on a line in Moving Pictures about Ponder never leaving the University again after getting hit by that Dungeon Creature.
"Hey, Ponder? Me and the rest of the lads are going out for the night."
"Alright." Ponder didn't even look up from the equations he was working on.
Adrian dithered in the doorway. "Um. Would you like to come?"
"Not really. Er, thanks, though."
"'Cause I noticed you don't really go out... ever..."
Ponder's pencil faltered in its quest through a forest of numbers. "That's right," he said blankly. It wasn't really a warning tone, but it held a note of discord.
But Adrian had more than a little of the spirit of a true wizard in him and pressed on. "Is there any reason...?"
"The last time I tried to, it didn't really turn out well." Again, harmonics at odds with basic Ponderness laced the words.
Adrian hazarded a joke. "Why, did Dungeon creatures break... into..." He trailed off as his teacher gave him a long cold stare.
"From fifty stories up," said Ponder in the glassy tones of someone walking down the mugger-infested back alleys of Repressed Memory Lane.
"Oh." The student wizard switched gears. "Well, it's probably not going to happen again, is it? Like, you know, lightning hitting twice or something."
"Maybe," Ponder admitted slowly. Truth be told, after some of the problems he was working on, he could use a nice layer of alcohol to insulate his brain for awhile.
"Yeah," Adrian continued, trying to jam a wedge into the crack. 'It's probably a million to... one..."
They froze. Logic was well and good for trying to pick apart the universe, but you couldn't just ignore the way things were.
"On second thought--" Ponder began, then stopped as he heard Hex stir behind him. The ram skull wheel turned, ants circulated through tubes, various occult accoutrements did their mysterious work.
The two wizards watched as the quill scribbled out a message.
+++Actually, It's A 5,244,325-To-1 Chance.+++
Ponder stared at the interjection. Despite the total lack of any features or tone, he could swear the machine was being smug. "So now Hex is arguing, too," he observed blankly. "Fine. I give up. Let's go, then. I need a drink."
Adrian led his unresisting teacher off to the greener pastures of inebriation.
As it happened, a failed spell elsewhere in the university ripped a big enough hole on the threadbare fabric of space and time for awful things to escape, and a recently-vacated section of the HEM building was destroyed in the fall-out... Which proved that someone somewhere has a very odd sense of humor.
