The apocalypse in question came in the form of a seven foot tall demon with bright red skin, a lot of very sharp pointed teeth and terrible halitosis, who had also been at the end of the line when it came to handing out names with vowels in them. The only person who could pronounce it correctly was Giles and even then he almost sprained his tongue saying it. Myrgggjkxrl. Possibly with a silent 'z' somewhere in there.
Anyway, the Big Bad Red (in the words of Buffy) came to Sunnydale with a host of minions (a mixture of vampires and bespelled humans) and had then settled himself in the ruins of the High School with a plan to open the Hellmouth beneath it.
When McGee had asked why the school had been built on that exact spot he was told the unpleasant story of the former Mayor of Sunnydale, one Richard Wilkins, which deepened his distrust of all politicians and left him making a mental note to check on Sarah's University, just in case the twit in charge was a delusional wanna-be demon.
Luckily Myrgg- Merg- oh hell, the big red demon did not have a reputation for being particularly clever. "Vicious," Giles had commented, "Homicidal even, not one of life's great thinkers."
"Great, I hate it when they get smart," a Texan voice had drawled from the doorway and McGee had then met the one Jedi he hadn't encountered so far. Lindsey McDonald was indeed Texan, with longish hair and a look in his eyes that spoke of humour and wisdom. "Sorry I'm late," he said, eyeing McGee inquisitively, "I need to have a word with a cousin of mine about the need to not piss off people in Interpol. Luckily I was able to prove that I was who I said I was at the airport."
"Lindsey, this is Tim McGee. Oz's new padawan," Xander said with a small smile.
"Good to meet you," Lindsey drawled as he shook hands with McGee.
"We don't have much training time, so he's doing it the hard way."
Lindsey looked at McGee again. "Whoa," he said. "Dagobah? That fast?"
"Yup," said Oz with a smile.
And then Giles broke in with the news that judging by the supplies that whatisname was bringing in, he obviously intended to open the Hellmouth with some kind of ceremony, so they needed to find out a lot more about it as quickly as possible. Various people had grinned at this and then vanished when McGee wasn't paying attention, like a group of anti-Gibbses. It was uncanny.
The news, when the next meeting was convened a few hours later, (McGee spent the time meditating and wondering how they were going to beat this demon) amused Giles massively, judging by the chuckling and the rolling of his eyes.
"Oh dear me. He's going to call upon Bast to open the Hellmouth? What a deluded little tit. Oh dear oh dearie me. Pillock." He looked up at the upraised eyebrows that ringed him and then he smiled and pulled himself together. "Best, or Bastet as she was known later, was a major Egyptian goddess, with the head of a cat. Originally she had the head of a lion and then later a lioness, but she's best known as the cat-headed goddess. Daniel can tell you more about the legends that surround her.
"I however, can tell you that if this is the goddess that Myrgggjkxrl is hoping will assist him in opening the Hellmouth, he's going to have a nasty shock."
"Why?" asked an intrigued McGee.
"Have you ever owned a cat Timothy?"
"Erm, no. I'm allergic to them. My family prefers dogs."
"Well, from my experience cat goddesses tend not to be very cooperative. Not unless they want something from you. And I'm guessing that Myrgggjkxrl doesn't know that and also lacks anything that Bast wants."
And so it had proved. The Scoobies (and wasn't that a weird name that he had to get to the bottom of) had put in a textbook assault on the High School, coming in on two axes of attack and taking out the demon's minions as they went in no time flat. The vampires were dusted, which one falling to McGee with his first real sword. It had had its game face on and seemed to think that he'd be a pushover. It had thought wrongly. His palm had stung quite a bit afterwards from the impact the blade of shearing through its neck. As for the humans they'd all been knocked unconscious.
By the time that they got to the shattered remains of the Library they'd discovered that Myrgggjkxrl was very close to completing the ritual and in fact as the last vampire shattered into motes of dust from a lightsabre to the neck he clapped his hands and shouted the name of the cat goddess at an old-looking idol of Bast in front of him.
There had been an odd shudder in the Force, the hairs on the back of McGee's neck had shot up and then he'd watched in horror as the idol opened stone eyes and then looked around the room. Then it focussed on Myrgggjkxrl, who looked very pleased with himself, before hissing something in Egyptian and then closing its eyes and going back to sleep.
Myrgggjkxrl had sat and stared in disbelief before staring back down at the book in front of him and then flipping back a few pages. Hearing a meaningful cough from one side the demon looked over to see Buffy standing next to him and then made an 'oh shit' noise. A millisecond later her sword removed his head.
"Giles," she asked as they all trooped out of the school, "What did stone kitty woman say to whatisface back there?"
Daniel laughed and then when Giles made a courtly gesture of encouragement he cleared his throat. "Buffy, Bast told him to get lost, as she was lying on her back with the sun on her stomach, having a nap, and didn't want to get involved in any nasty Hellmouth stuff that might get gunk on her paws."
"Ah, kitties," Buffy grinned. "Always up for a belly rub."
McGee smiled and then looked over at Oz, who had approached him. "Time to restart your training."
