Summary: Fluffy domestic fic with a teenage William. Followed by two different accounts of Bad Blood as the plot thickens.

Part 1: "No. Way!"

Mulder pulled the parking brake as his Honda Civic comes to a stop across from Glenview Park High School. He takes out the Android from his pocket and mutters an impatient 'Damn it!' when his battery displays a meagre 5%. He can never understand how Scully always manages to keep her phone so well charged. He's never seen her battery drop below 50% whereas his has the tendency to dwell in the low percentages on the days when it's not actually half-dead.

'Come on old boy. Just one quick text message... You can do this.' Mulder quickly locates the strange yet familiar name on his modest contact list as he types the brief message:

'I'm here.'

Mulder has hardly put his phone to the side when its screen blinks with the notification:

'William: "I'll be out in 5 mins."

Mulder's heart almost skipped a beat when he sees the name on his phone. It's been several months but he still cannot believe this is happening. Scully, him, and William. Together, at long last. Just the thought of it both overwhelms him and makes his heart swell with joy and gratitude, if not a little disbelief.

Scully and Mulder are back at the FBI now. In the past four months or so, they would pick William up at school on their way home from work during the days he comes to live with them. It felt quite strange at first, this domestic normalcy: William climbing into the back seat, all sweaty from his basketball practice, shuffling his backpack aside while trying to make himself comfortable in the rather limited leg room in the back. William has grown quite tall now, a sure 5"8 with a lanky yet healthy form just like his dad. Scully soon sensed her son's discomfort judging from the accidental bumps on the back of her seat whenever William was trying to move his legs around. Every time William comes over, Scully would remember to crank her seat forward so her son could have more space. As William's stays grew both in length and frequency, Scully stopped pushing back her seat and just kept it way up in the front. She never needed much leg room anyway.

But the best part is always William's greetings as he opens the car door: 'Hey mom, dad.' At first the words 'Mom' and 'Dad' were muttered rather meekly and for a brief second all three of them would tense under the unfamiliarity. Now, the hesitance no longer exists. Any initial unease was replaced by a comforting sense of warm familiarity. It feels pleasant and somehow re-assuring for William to call them 'mom' and 'dad' as the words come naturally to him. For Mulder and Scully, every time their son utter those words, their heart still skip a beat. After all these weeks, they still find it hard to wrap their head around the reality that William is here. Their son is here. The three of them. Together.

'Hullo Dad!' William's call jolts Mulder out of his reflections.

'Will! Come sit in the front with me.' Mulder flashes a happy grin as he unlocks the door and motions his hand at the seat next to his.

'Ok but dad, where's mom today?'

'She went home early this afternoon. It's just you and me this time, Will.'

'Geeez! Dad, how can mom possibly sit in such a tiny space? She could have pushed it back a few notches!' William exclaims as he cranks back the seat as far as he can.

Mulder cannot help but laugh:

'Hah hah she actually pushed her seat forward so you have more room back there. But don't worry Will. Mom is tiny! Uhm… no, I mean petite. Trust me, I've been driving with her since forever and I know she's more than comfortable with that little space. Anyway, how's school?'

'So so, dad. Oh, we were talking about ideas for the school play this Halloween. And so far most of us seem to agree on vampires.'

'Vampires? Interesting! Hmm…' The idea catches Mulder's interest immediately and he is already itchy to have a conversation with William on this colourful topic. Mulder almost wishes Scully was here so she can roll eyes at him as tries to impress William with his knowledge on vampirism.

'Do you know, William, there are as many kinds of vampires as there are cultures who fear them? I mean there are fanged or without-fang vampires, blood-sucking vampires, manure-eating vampires, and even vegetarians as the list goes on!'

'Whoa dad vegan vampires?'

'You heard me. But what kind of play are you planning on, anyway? What are the vampires doing in there? The typical blood sucking, melting away at the sight of the cross and all that?'

William slightly rolls his eyes and lets out an exasperated sight. This gesture reminds Mulder of Scully when he calls her to do an autopsy at some ungodly hour or when he rambles on about his wild theories.

'No, dad, I wish! I wanted to do something Bella Lugosi, you know, Nostefaru and stuffs, I mean the original Bram Stoker would be awesome too! But somehow most of the girls in my class insisted on doing this Twilight thing and because more than half of the class are girls, we were outnumbered so there you have it, Twilight.'

'And can you explain to your ole' pap what this Twilight is? I've spent quite some time poring over the vampire archive but somehow I don't think I remember seeing it.'

'You won't find it in your official or academic archives, dad. It's a popular fiction thing. Something about a normal girl with a vampire. And apparently this vampire is really attractive because the main character is head over heels into him and so are the girls in my class apparently. So yeah, ours Halloween will be a play about crushing on vampires, literally. I mean, seriously though! What can be so attractive about overgrown teeth and red eyes?'

Mulder gives his son a mischievous wink: ''Whooa William you have no idea how many people can find big teeth attractive.'

'Dad what do you mean? Don't tell me you're one of them?'

Mulder chuckled 'No, I'm not. But I know someone who does. There was this case long ago. Exchanging flirty glances with a vampire right at first sight, no less. And a vampire with huge and uneven buck teeth at that! Hoo boy… You can't help but think he hasn't seen his dentist for decades!'

'Haha flirty glances? With a guy, no, vampire, who has huge dirty buck teeth? Dad who on earth can be so funky? Is it someone I know?'

Mulder is quick to put on his mysterious holding-back-information Sherlock look as he winks as William: 'Yes, it's a person you know. Take a guess, Will. But here is a hint, think of someone whom you can never imagine doing that.'

William gasps, staring wide-eye at Mulder. The boy looks just like his dad when he saw a UFO for the first time. 'Dad you don't mean it's…?'

Mulder can hardly keep himself from laughing as he sees the incredulous look on his son's face: 'Yep. That's the one.'

'No way!'

'Wayyy…'
