Season 3 "Dopplegangland"
"I thought you were all anti-magic after that spell." Buffy said as she watched Xander and Willow place various jars in a circular pattern on the library floor.
"I actually kinda got interested in it, despite the headache the first spell gave me. It was kinda cool to be in the know."
"Well geez, give me credit why don'tcha." Willow said.
"Oh, Willow's been helping." Xander added.
"Thank you," Willow nodded her, Buffy giggled at both of them.
"Just make sure you guys are careful, I don't want anything happening to you two."
"We're totally careful," just as she said this, Xander lit a match and accidentally dropped it on the parchment in front of him. It caught serious blaze.
The three stood up, Buffy stomped the flames out. She and the redhead gave Xander 'the look'.
"What? It coulda happened to anyone."
Later
After the gang's session in the library, Xander was off to 3rd period. He passed through the busy halls and made his way to the staircase, where he bumped into a brunette girl. She spilled all of her books; Xander placed his down to help her gather her things.
"Sorry, it was my bad."
"Yeah, it doesn't take a genius to realize that." The girl snapped as she grabbed her history book.
"Okay. Bad mood?" Xander asked, grabbing two more books.
"I really don't feel obligated to tell you that," the two stood and came face to face. "Please hand me my things and let me be on my way." Xander handed her the books. She took them before briefly glancing in his eyes. The brunette looked at him as he were god himself, a sudden twinkle emerged in her hazel eyes. "You're Xander Harris, right?"
"Yes, and I'm amazed at how fast you go from disliking me and now suddenly interested."
"Oh, sorry about that. I'm Anya, Anya Jenkins." She held out a free hand, Xander shook it.
"Hello Anya,"
"Look, I know this is kinda sudden but…"
"A movie and dinner will do just fine," Xander joked.
"That's funny, but no. I heard that you kinda dabble in the black arts."
"I dabble, I dip and occasionally flip. Need help with a spell?"
"Actually I do."
Later
Images of death and carnage flashed before the boy's eyes. Willow bit him and slashed a deep cut to her chest; she pulled him to it and let him drink the scarlet blood. He roamed the city with Willow by night, slaughtering innocents and feeding off their remains. He even shared Cordelia's precious neck with his redheaded companion.
The images grew blurry and passed by quickly, but the last vision freaked him the most… he grasped Buffy's neck and slit it clean off.
"What the Hell!" Xander came out of the trance; he jumped from his spot on the floor.
"It didn't work," was all Anya could say.
"What didn't…what were… who the hell are you and what was that?" Xander managed to muster up the words.
"I never should've trusted an incompetent little boy." Anya snarled.
"Hey!"
"Leave me." She demanded.
"I want my questions answered."
"LEAVE ME!" she protested louder. Xander jumped.
"Okay, leaving." He grabbed his things and left the dark classroom.
Was that my future, was I destined to become a vampire, rule Sunnydale with Willow and…kill Buffy? That was all he could think once he entered the hall.
At The End Of Town
Swirling dust appeared out of thin air. It slowly formed in the appearance of Sunnydale High School Student, Xander Harris. The scarred, beaten and vamped out figure fell to the ground. The monster looked up, slightly confused.
"Where the hell am I?"
