Xander finished off his letter to the Mayor by reminding this sorcerer the younger man fully understood that after his death, Wilkins was perfectly free to do whatever he wanted in also killing the Scooby Gang and anyone else that had the slightest chance of knowing the politician's secrets. Trying to stop this by using the sorcerer's own magic in sending pre-cast spells to directly attack Wilkins right after he came back to life in City Hall wouldn't work, since the protective wards around him there created by a century of sacrifices would handily shrug off Xander's hexes at their current level of power, and using more Hellmouth energies risked severe collateral damage that wouldn't just stop at the town's administrative center being destroyed. It was entirely possible that if Wilkins was attacked elsewhere besides City Hall, the entire town might be reduced to rubble. Nope, what Xander had done was to set up something that would keep good ol' Dick as busy as a bee.
A grimly-amused teenager then carefully wrote out the name of a certain spell that Wilkins had learned decades ago, but had also never used in all that time, for very good reasons. After all, the whole point of becoming an anonymous small-town government official in Sunnydale had been to avoid the attention of other magic users.
The Fellowship of the Coven spell had been around for centuries, a minor enchantment that sent a sociable salutation by a witch, wizard, kenning woman, mage, or any other being possessing supernatural powers to their friends or acquaintances having those same abilities. Kind of like a computer e-card. Anyway, it had fallen out of favor long ago, since this spell had the minor drawback of being extremely easy to trace, and after sending that greeting, various magicians had been located and murdered by their enemies following this magical communication. Still, the cantrip remained very effective in reaching those it had been sent to, being incredibly difficult to be blocked or impeded by anyone, no matter their level of mystical power, which appealed mightily to a young man desperate to protect his friends.
Explaining further in his letter, Wilkins was flatly told by Xander that he'd used the last of his Hellmouth energies to set up some final spells that would start the instant the Janus statue was broken. One spell would continually check his friends' life signs, and if the Mayor tried anything, the Fellowship of the Coven spell would instantly go right out, causing every single magic user in the world to receive the following message: "Howdy do, everyone! Richard Wilkins I, II, III here, on the beautiful Boca del Infierno in sunny California! I was feeling a little bored being the Master of the Hellmouth, so y'all come down, and let's boogie! Betcha I can win all the limbo contests before I turn into an Old One and gobble up everybody on earth!"
Finally opening his eyes, Xander smirked at his completed letter, as he used his magic to make two copies of this, sending one away to a currently-unoccupied office in City Hall, and teleporting the other note into his suit pocket. Next, as promised, the teenager set up his precautionary spells. Carefully using his mystic vision to confirm these were properly done and ready to go off if necessary, Xander paused, as he wondered if he should have added a little more information to his letter. Shrugging, the high school student reminded himself that Wilkins was a very smart man, and that sorcerer didn't need to have everything spelled out to him. After an extended lifetime of learning patience, the Mayor would surely be able to control his temper long enough for him to work out how to destroy the Fellowship of the Coven spell without setting it off. In the meantime, he'd refrain from harming the Scooby Gang, with that politician only keeping a close eye upon the group, which in turn would eventually cause him to grudgingly realize that none of them knew anything about his secrets, and hopefully decide to leave them alone for the present.
In the costume shop, Xander huffed a deep sign of resignation. That was the most he could do for his friends; now they were on their own, to perhaps someday learn the truth about the Mayor in time to stop that sorcerer from becoming an Old One. Despite knowing how powerful Wilkins was, the teenager was still fairly confident the Scooby Gang would win in their coming battle with the politician, if only because of exactly what that master of Sunnydale was so ludicrously planning to do to himself. *I mean, a giant snake? Sheesh…*
Shaking his head in weary exasperation, Xander looked at the small statue before him resting unassumingly upon the register counter, and he became much more subdued as his hands again grasped the carved stone, fingers curling around the double faces of Janus. Lifting the bust to his head level, Xander closed his eyes in preparation for his final actions as Mayor Wilkins, tensed his muscles, and-
Yet again, a flash of insight suddenly appeared in Xander's mind, causing him to abruptly halt before he could hurl the statue to the floor, as this unexpected inspiration overwhelmed his brain.
It was…
Horrible. Terrible. Awful.
Still…it might work. And even if it didn't, how the hell could it make matters any worse?
Opening his eyes to stare straight ahead as he absently lowered the Janus statue to be held in his hands at waist level, the high school student queasily admitted to himself that there was no possible way he would've thought up that appalling idea all on his own, even just yesterday when he'd happily been ordinary Xander Harris. Now, however, he was Xander and Hyena and Wilkins and… Yeah, even Ethan Rayne, whose Chaos knowledge he'd just absorbed, along with everyone's else personalities and memories and urges for survival. They'd all come together to think up this last-second scheme, which he was…seriously considering.
No, Xander bleakly corrected himself, not considering. Consenting. It was either that or death, anyway, which helped the Sunnydale native to finally make his decision, which was not easy at all, but rather, inevitable.
As he turned around while still carrying the little statue, Xander grimly noted to himself that during the following decided course of action, he needed to rapidly say four specific words, all while carrying out four actions as quickly as possible. Which was undoubtedly the result of one last cosmic joke being gleefully played upon Mr. Xander Harris, butt-monkey extraordinaire, by the Hellmouth itself.
Reaching the proper spot in the costume shop, the mature man carefully knelt down on the floor, and while on his knees, Xander lifted the Janus figurine in his hands over his head, and he closed his eyes. A moment later, he guiltily opened them, while bitterly telling himself, *You chose this, so you watch it all, dammit!*
Taking a deep breath, Xander then roared out, from the very bottom of his lungs, four words that echoed throughout the costume shop, while simultaneously banishing every magical shield he'd previously had around himself to protect himself from the Chaos magic, crushing with greater-than-human force the double-faced carving in his hands, while bringing down as hard as he could the Janus statue already beginning to crumble directly upon the back of an insensible Ethan Rayne's head, shattering both stone and skull in one savage blow.
