Chapter 4 - Buffy's Back!

Friday 6.15pm

Jenny's Dinner

Buffy: Well hello to you too Harmony

Lilah: Oh so you know these people you don't strike me as the type to have any friends.

Buffy: Shut up Lilah and they're not my friends........ Does it even really matter?

Lilah: Okay I'm sorry but I'm going to report this to Jenny you've been slipping up Buffy and we've been getting a lot of complaints from people. (She then turns and leaves)

Cordelia: I'm not surprised I mean you can't do anything right Buffy. You screwed your sisters' boyfriend, which made you look like a major slut I have to say, and then you run away and BAM you're back and knocked up with some freaks kid. You are a BIG screw up!

Buffy: You know Cordelia why don't you just SHUT THE FUCK UP!!!!!! You don't even know who I am or anything about me just a whole load of lies you've heard from your bitch friends sitting at this table with you –

Willow: - I'm no bitch Buffy I think that would be you I mean you're the so called 'friend' who disappears for 4 months without telling anyone where you went so I think you are the one who should be called the BITCH!

Buffy: OH MY GOD WILLOW! Did you just say the B word I'm soooo shocked and I didn't think you had it in you, I mean you've always been the geek with your head stuck in your books and that innocent blush you used to get whenever you talked about Xander and how you wanted him to be your first and OH SILLY ME!! I'm sorry I wasn't supposed to tell anyone that oh well I mean its okay I mean I haven't told Oz about the time you almost sleep with Xander.........oh wait I just did silly me again.

Oz: (turns to look at Willow) Is that true?

Willow: Well........

Oz: I can't believe you. (Pushes out his chair and runs out)

Willow: (crying) How could you do this to me Buffy (turns and goes after Oz)

Harmony: You are so sick!

Cordelia: You want to mess up everyone else's life just cause you screwed up yours, well that's just plain evil.

Angel: (stands up and talks in her face) Yeah Fluffy why don't you go find your freak and go back to trailer park where you belong you piece of SHIT!!!

Buffy: (smiling and wiping her face) Thank you very much for that shower of shit really refreshing!! But I don't think Spike lives in a trailer park.

Spike: What the hell does this have to do with me?

Buffy: Well you are the 'freak' father of my baby as all you friends are saying.

Spike: Stop bull shiting Buffy. You probably –

Buffy: Nope you what happened that night Spike and as they say it takes two to tango. (Giggles) I've always foun-

Spike: This isn't a joke! I'm not the father of your kid!

Buffy: Yes you are I was pregnant before I left Sunnydale and I know for a fact that this baby is yours because I've only been with one person okay!! And you can deny it all you like Spike but at the end of the I will drag you to court and make sure you pay child support and who knows what else could happen I mean I am under age...you could be charged for taking advantage of me.

Spike: Are you threatening me?

Buffy: Well Duh!! We can take a paternity test just so I can prove it. I'm willing to its up to you or you can do the math and work out that if I'm 4 months pregnant and I sleep with you 4 months ago then BAM! The baby's yours! Now I'm going and I'll contact your lawyers and see when we can meet and discuss how much child support you will pay.

With that Buffy turns and starts to go but is stopped by Spike.

Buffy: What do you want and could you please let go of my arm before I scream!

Spike quickly releases her arm.

Spike: Look can we please just make an agreement because I don't want to involve lawyer and stuff.

Buffy: Well that's a great idea but I can't talk right now I have to get back to work or I'll be fired. So can we do this some other time?

Spike: Fine then meet me at Starbucks tomorrow say around 1.30pm.

Buffy: Sorry I can't I'll be I've got an appointment oh wait a minute you can come with me!

Spike: No way!

Buffy: You have to because my doctor wants to meet you and get record of your family history you know if anyone had diseases, twins, skin problems, triplets –

Spike: Wait a minute my dad has twin but that's it no disorders or anything like that.

Buffy: But you still have to come Spike just this once and that's it.

Spike: I can't Faith wouldn't want me to come.

Buffy: Whose Faith?

Spike: She's my girlfriend

Buffy: Oh I see you have a girlfriend!

Spike: Why are you so upset?

Buffy: Well maybe because you broke up with and said those.... those mean things that you said but I cant remember but...anyway they hurt me! How old is Faith?

Spike: She's 18.

Buffy: She still in high school then?

Spike: Yeah...

Buffy: Well that's confusing I thought you didn't date high school girls

Spike: Yeah well Faith's different more mature than other girls and she's going to UC Sun- Why I am telling you this?

Buffy: I don't know. But you have to come to the appointment you owe me, for breaking my heart and all the pain you caused me and also for getting me pregnant.

Spike: (sigh) Fine then but don't tell anyone and especially not Faith she'd freak out!

Buffy: Okay and whose Faith?

Spike: I already told you she's-

Buffy: Yeah I know she's your girlfriend I meant what does she look like?

Spike: Brunette girl, brown eyes.

Buffy: (surprised) the skinny one?

Spike: No not Fred, the other girl who was more curvy wearing the black.

Buffy: Figures. Not really surprising. So anyway meet me outside Sunnydale Hospital 2.00pm okay and don't be late! Bye!

Buffy then leaves and disappears through the back door of the restaurant. Spike then turns and heads back to the table.

Cordelia: That took a while.

Spike: Yeah well Buffy is very hard to persuade.

Faith: I need to go.

She gets up and leaves with Spike chasing her

Spike: Faith wait!

Faith: What is it?

Spike: Look I'm sorry

Faith: Well it's not gonna change anything you got another girl pregnant and I know it was before we were together. But its gonna change things between us I mean your gonna be a Dad and your gonna need to be there for your kid and I ...I don't see how we're gonna work out.

Spike: I know but we can make it work can't we I mean I can arrange with Buffy days I'll she the baby and stuff and we c-

Faith: No we can't! because it's not just about you! This is gonna affect me as well and my life and no its sounds selfish but I'm not ready to throw my life away in helping you raise your child I'm only 18 and I'm not ready for kids yet. So I'm sorry Spike but I don't want to with you unless you have nothing to do with your kid

Spike: You can't make me pick between you two that's not fair Faith. I can't abandon my baby.

Faith: Then I guess we're over.

Spike: Yeah. See you around.

Faith: k bye.

Spike: Bye
