Here's Part 12:

"Hey, watch where you are going." Oz commented as some guy bumped into him.

"What do you know, dog boy is back in town." Spike snickered with a grin on
his face.

"Spike, I would love to continue this conversation, but we
don't have time for you." Oz pulled Buffy by her wrists.

"Fine, just walk away from me now that I'm no threat to you. When
I get this chip out of my head, I'm going to..." Spike got cut
off by Oz glaring at him.

"Oh yeah, you are not going to do a single thing. You hurt anybody
I care about, the chip will be the least of your problems." Oz was
getting angry, and surprisenly beginning to show it.

"Bring it on, then mate or  all werewolves all bark and no bite?" Spike
was itching for a bloody good  fight.

"Hey, the two of you, cut this macho crap out. Oz, we have to get
my body back. Spike just wants to get under your skin." Buffy
knew that Spike wanted to stir up some trouble and they didn't have time for that.

"Yeah, Buffy." Oz knew that getting Buffy's body back was more important
than kicking Spike's dead carcass. "Sorry, let's get going."

"Did he call you the Slayer? I was..." Spike didn't get what was
happening.

"Yes, Spike,Faith and I, switched bodies." Buffy told  a very
 surprised Spike.

"Hmm, Slayer, you wear Faith really well." Spike grinned with
lust in his eyes.

"Spike...please shut up." Oz and Buffy said in unison,
before entering the Bronze.
