One week later

Xander knocks on the front door of Buffys house dressed in his Janus costume. 'Wow. I finally have everything all together. It was harder than I thought to get everyone to wear costumes that will help them in the future. The vampire attack 6 days ago has really help set me up for the foreseeable future I mean who expects a vampire to have 10 Grad on him. I still have$9500 left. The costumes for tonight though are totally worth the 500 dollars spent on them.'

Flashback 4 days ago

The bell to Ethans rings as Xander walks into the costume story that Janus told him to shop at. 'Wow nice selection.' Xander thought.

As Xander was walking through the store pick up a couple fake laser guns, paints for the remote, a mix of Jedi robes and other sci-fi costumes for the Janus outfit, he sees some interesting costumes for everyone.

'I think I should get costumes for a couple other people besides Buffy and Willow. I mean the more help the easier this task Janus has set will be. Lets see who else to get a costume for definitely G-Man and Jenny. I got it. Why not get one for Mrs. Summers and Dawn? Ok, now that we have everyone chosen time to get the costumes,' thought Xander.

Again walking around the store, he sees the perfect costume for G-Man. As Xander picks up the Methos costume from the Highlander movie, the shop owner steps up quietly behind him.

"Do you need any help getting your costume?"

"Yahha, dont do that. You really shouldnt do that in Sunnydale," said Xander.

"I am sorry. Its a bad habit of mine," said the shop owner.

"I dont need any helping getting my costume; I have already picked one out for me. I am currently looking at getting some costumes for my friends. I think this Methos costume would be a great costume for Giles."

"Rupert Giles? I think that would be a great costume for him," asked Ethan Raynes. 'This will be fun catching Ripper in the chaos.'

"Yea, G-Man is the librarian at the high school", replied Xander.

Looking around the shop, Xander seeing Buffy heading to the noble woman dress, he realizes that it would be a bad costume to wear this night. Xander head over to Buffy. Ethan Raynes following.

"This looks like the perfect dress for you. It reveals the inner Princess," said Raynes while thinking 'This would add to the chaos with the Slayer dressing in such a helpless costume.'

"Its way too much money", replied Buffy thinking that Angel would love her in that costume.

"I am sure we could work out a deal," states Rayne.

"Hey Buffy, that costume has some potential. I have an idea that that would go great with that costume and if you go with this as your costume, I will pay for it. I think you should add a sword and go as a very old Immortal," offers Xander.

Buffy smiles thinking that it would be a great deal.

Xander then sees Willow going for the ghost costumes and askes, "Willow, this year you show go as a different costume than a ghost. As a favor for me, please go as a very talented white witch? Please."

Willow giving in takes the white witch costume. Now that Xander had picked out his friends costumes, he heads off to get a costume for the rest of the group. As Xander walks around the store he picks up a Toni Stark costume (a female Iron Man costume) for Jenny, a Washu costume for Dawn since he knows that she like Anima and a Dr. Beverly Crusher costume for Mrs. Summers.

Now that Xander has picked out his costumes for everyone, he purchases everything.

End Flashback

Xander is brought back to the present, when Mrs. Summer opens the door.

"Wow, the costume looks great on you, Mrs. Summers", says Xander.

"Thanks, Xander. And thanks again for the costumes," said Joyce as Dawn runs down the stairs to greet Xander. Joyce heads into the kitchen to finish what she was working on before Xander arrived.

"Great costume, Xander. What are you supposed to be?" asked Dawn.

"I am dressed as Janus, who was a member of an advanced race known as Alterans," replies Xander. Xander looking at Dawn thinks 'Wow she definitely looks older than 15.'

Just as he finished with that thought, Buffy comes down the stairs.

"Wow, I definitely renounce spandex, Princess Buffy. So do you have the sword? I was thinking you could add a stake and go as a 6,000 year old Immortal Slayer. It would be a great unique costume," says Xander.

"Why thank you kind sir. Buffy then pulls out a sword and says I like that idea. It definitely makes it an interesting costume, thanks. Willow should be down in a minute." Just then Willow comes down the stairs in a beautiful set of white robes and a wand.

Xanders jaw drops. "Wow, amazing costume, Willow you look great in it."

Willow blushes.

"I guess its time to get the kids and to go," says Buffy

An hour and a half Later (its 7:44 PM)

Xander pulls out the note in Alteran and looks down at it. Just as he does so, he feels a wave of power flow through him and the rest of town.
