Air pumped painfully in and out of her lungs as she ran for all she was worth. Just a few more yards and she would be safe. A few more yards and then Xander could stake the vampire who was hot on her tail. She sighed in relief as she caught a glimpse of Xander's orange shirt in the trees. Slowing down she came to a stop. Turning around she saw the confusion on the vampire's face before Xander walked up behind him and he turned to dust.

"Well, that was easy," Xander said cheerfully.

"Says the guy who stood and waited for me to bring the vamp to him. How about you be the bait next time?" Andrea replied sourly.

"Oh come on, sis. It couldn't have been that bad. It's not like your first time when we were in the graveyard instead of the park and you had to dodge the gravestones," Xander said swinging an arm around his sister as they walked toward their parked car.

Andrea huffed in annoyance but snuggled into her brother, showing him that she wasn't really mad. Moving towards the car, she thought about how much their relationship had changed since they had met Buffy two years back. They had always been extremely close; they were twins after all. But when they had got to high school they had stopped spending so much time together. She had gone off to become a cheerleader, while Xander had devoted his time to Willow and Jesse. Andrea had always like Willow but could never stand Jesse, and had used cheerleading practice and hanging out with her new friends as an excuse to avoid him.

It hadn't helped that her new best friend, one Miss Cordila Chase, thought that her brother and his friends were losers. But when Buffy had showed up and befriended her and her brother as well as his friends everything had changed. Now that she knew what was really going on in Sunnydale she couldn't turn her back on it, especially when her brother seemed content to throw himself right in the middle of it. So she befriended Buffy and Willow and dragged Cordy along with her. It wasn't easy at first, but after a while it got better and soon she and Xander were extremely close again.

She still did cheerleading but she was also an official member of the so-called Scoobys. Normally, on nights like tonight she would patrol with Buffy while Willow, Cordy and Xander did the other side of town. But ever since Buffy left after casing the Master, things had been a little more uncoordinated. For the most part she would patrol with Xander while Cordy and Willow went out with Giles. On nights like tonight, when it was just her and Xander trying to cover the whole town while Cordy and Willow helped Giles research, she thought about why she joined up in the first place.

Thank God that it was nearly five in the morning and the sun would be coming up soon. Today was Saturday, so as soon as they got home and cleaned up they would be able to sleep their numerous bruises off. They were almost to the car when she heard a noise coming from behind them. Not wanting their stalker to know she knew they were there she squeezed Xander's shoulder heavily and kept walking. Understanding what his sister was trying to signal to him, Xander reached into his lower back pocket seemly looking for keys while he wrapped his hand around a stake.

Moving apart quickly they both turned and slid easily into defense mode. Seeing that their opponent was a lone vampire, Andrea was tempted to move out of formation. But she stuck with the training she had received from Giles and waited for the vamp to make the first move.

"Well what do we have here? Two of the slayer's minions, and no slayer in sight. I guess I'll have to settle for you two then. Pity, I was looking forward to a good fight," the vamp said, looking rather pleased with himself.

"I don't think you want to be doing that, mate," Spike said, walking out of the shadows.

"Spike, what the hell are you doing here?" Andrea asked extremely nervous at being faced with the master vampire.

"Ahh, we'll get to that part in a little bit. For right now, just be grateful I don't let City Boy here eat you." Spike answered while sending a leer her way.

"As if he could." Xander said.

"Oh I'm sure he could, but we are not going to wait here and find out. Don't want to be wasting my time, now do I?" Spike said. Andrea watched as he turned to the vamp in question and went into game face. The other vampire took off at a sprint, never looking back.

"So what do you want with us Spike? You know as well as everyone else that Buffy's not here. So we won't do you any good as bait," Andrea said.

"It's not bait I need," Spike said before turning to look at the two of them.

"Then what do you want with us?" Xander demanded.

"Well that's for me to know and you to find out, kiddos," said Spike as he turned away from them.

They both felt their skulls explode in pain before they passed out.
