Okay, so first off, this is never going to be as funny as the episode – which is one of my absolute favourites - so I'm not even going to try! But I hope it's still amusing. It's not an exact version either, as I've changed most of the shows-within-a-show and genderswapped some of the other characters along with the Winchesters.

For anyone who hasn't read the previous 'sisters' stories: Dean is Tara, and Sam is Alex and their backstory is virtually the same

Changing Channels.

1.

Another day, another job. Another shitty motel.

Alexis Winchester sighed, checking her reflection again in the tiny, cracked bathroom mirror. This motel wasn't actually all that bad, compared with some places she'd spent the night. At least there was hot water; it made trying to pass as an FBI agent that much harder when you hadn't been able to shower for days on end, or had been forced to sleep in the car.

Still, this case looked interesting. Weird, but hopefully the more 'usual' kind of weird they could actually deal with. You know, no Horsemen of the Apocalypse, no Antichrist, no monsters pretending to be Paris Hilton. That would be good.

She went back into the room, where her similarly suited sister was perched on the edge of the bed, watching TV. Alex frowned.

"What the hell are you watching?"

Tara started, guiltily, quickly switching the channel, but it was too late.

"I know you spent the day as an eighty-year-old recently, but-"

"Oh shut up, Lexie. I was just channel-surfing."

"I mean, if you're gonna watch a talk show, you could at least watch Ellen. What was that, anyway?"

"I dunno. HRT in programme form. You ready?"

"Uh-huh."

Tara got up, surreptitiously checking her figure in the full-length mirror on the wall before heading out. She thought Alex hadn't noticed, but since the experience of being aged fifty years by a magic spell, Tara had been a lot more bothered about wearing bras.

The town Sheriff didn't seem best pleased to have 'FBI agents' turn up, asking a load of questions and generally making his day harder work than he'd have liked. But the Winchesters were more than used to that.

"So you don't think it's strange, one of your locals getting his head ripped off?" Tara was asking.

The sheriff shrugged, far more complacent about the incident than you might expect.

"Where the Randolphs live, way up in high country? It's pretty wild up there. You get bears. Things happen."

The sisters absorbed this.

"Things like... a bear chasing Mr. Randolph through the woods, smashing through his front door, following him up the stairs, and killing him in his own bedroom?"

Tara raised her eyebrows.

Sheriff McDonald shrugged again, reaching for the coffee pot.

"Like I said, it's pretty wild up there."

"And... you're sure it was a bear?" Alex asked.

"Well, what else could it be?"

"Never ask that question," Tara muttered.

"And the wife?" Alex tried to keep the conversation on track.

"She witnessed the whole thing?"

The sheriff wouldn't meet their gaze.

"Look, Kathy Randolph went through a hell of a trauma. She's confused. The last thing this town needs is for same crazy story to start circulating about - aw, never mind it."

Both women's ears pricked up.

"Never mind what?"

Despite all Sheriff McDonald's protests, Alex and Tara soon managed to secure an interview with the grieving widow in one of the station's interview rooms. Confused, she certainly was, but not in the way the sheriff had said.

"I know, I know, it's crazy. It's impossible, I must have imagined the whole thing," she burst out, before they could even ask a question.

"But I know what I saw."

"And that was?" Alex asked.

"Well, it wasn't a bear. But what's the point? You won't believe me either."

"Try us."

Tara leaned forward, her interest piqued.

Kathy Randolph hesitated, defensive.

"It was the Incredible Hulk, okay? My husband was murdered by the Incredible Hulk."

A brief silence greeted her words. That... was a new one. Whatever Tara and Alex had been expecting her to say, it wasn't that.

"You mean... the big green guy?" Alex wrinkled her nose. "From the movies?"

"No, the TV Hulk."

"Lou Ferrigno?"

Tara looked genuinely interested in this development.

"That's the guy. Big. Green. Angry."

"Lou Ferrigno killed your husband?"

Kathy Randolph folded her arms, sitting back.

"I said you wouldn't believe me."

"I wouldn't say that." Tara was almost enjoying herself. "We've heard weirder, if you can believe that."

"Really?"

Mrs Randolph seemed quite pleased to have found someone who didn't laugh in her face when they heard her story.

"We're sort of... specialists in weird stuff," Alex added.

There was another question Tara had to ask, one she'd never imagined anyone would, ever.

"Was there any reason why Lou Ferrigno would want to kill your husband?"

Kathy Randolph sighed, heavily.

"This sounds kind of heartless... I mean, he was my husband, but... he kind of had it coming."

"How's that?"

"Look, Bill and I... we haven't been love's young dream for a while, you know? And Bill... well, he hit me. More than once. Went to court and everything. And not just that. He used to get in fights whenever he went out in town, bar brawls mostly, but enough to get him put on one of those anger management courses. Not that they did much good."

Her audience took this in, considering the implications.

"So... you wouldn't like him when he's angry?" Tara asked.

Alex rolled her eyes, but Kathy Randolph seemed perfectly serious.

"Yeah, that's what that other woman said."

Both Winchesters sat up, alert.

"What woman?"

"Oh, nothing. It's just, I was in the store a few days ago and this lady saw my bruises-"

Kathy pulled up her sleeves, displaying four fingertip marks on each forearm, where her husband had grabbed her.

"We started talking, and she said it sounded like Bill needed to be taught a lesson."

The sisters exchanged a glance, a horrible suspicion starting to dawn.

"Is that exactly what she said?"

"Yeah. Something about Bill getting his just desserts."

"This woman... was she by any chance buying a bunch of candy?" Tara asked, leaning forward intently.

Kathy frowned.

"Now you mention it, yeah, she did have a handful of candy bars. Though I don't remember her actually paying for them."

Tara got to her feet, abruptly.

"Thanks for your time, Mrs Randolph. You've been very helpful."

She left the room immediately, Alex scrambling to follow her.

"You thinking what I'm thinking?" Tara asked, grim faced.

"Just desserts... has a sweet tooth, likes to screw with people before she kills them."

Alex didn't have to think too hard to put two and two together.

"So we're dealing with the Trickster."

"Yup. About freaking time we ran into that bitch again. You know, I try to make it a rule to gank anything that kills me even once, and she sure put that to the test at Mystery Spot."

But Alex was pensive.

"Tara, hold up. Are you sure killing her is the best thing here?"

Tara came to an immediate halt in the corridor, staring at her sister in utter disbelief.

"Are you serious? She iced me about a thousand times, remember? Long overdue a little payback."

"That's not what I mean."

Alex was thinking hard.

"I mean, yeah, you're right but... she's powerful. One of the most powerful creatures we've ever met. Maybe we can put that to use."

"You wanna hand out a little more poetic justice before we end her? We don't have the time, Lexie, and I sure don't have the patience."

"No, not that. I mean, look at the bigger picture. The Trickster likes the good life, she's not gonna be on the side of those who want to bring the party to an end, is she?

Tara was still staring incredulously.

"Wow. You're actually serious."

"Look, we have to start being creative, if we stand a chance stopping the world from ending."

"Do I have to remind you she just had the Incredible Hulk rip a guy's head off? What makes you think she'll play along?"

"I just think it's worth a try. If it doesn't work, then we'll kill her, okay?"

Tara sighed.

"The things I do for you. Okay, fine. We'll try."

It took the best part of the day for them to catch a glimpse of the Trickster again, this time a confused distress call over the police scanner that seemed to fit her MO. But when the Winchesters arrived at the scene, it was deserted.

"Oh goody," Tara remarked, sarcasm dripping from her words. "An abandoned warehouse. My favourite."

"And we got here before the police?" Alex added. "It just gets better and better, right?"

Tara pulled two stakes out of the trunk, tossing one over to Alex.

"Remember, if she tries to pull any of her usual shit, I'm staking her."

"So long as you let me talk to her first."

"I promise nothing, little sister."

They went into the warehouse.

Disclaimer: Nope, didn't invent Supernatural, or anything else in this, really. I've tried to choose shows that fit best with the episode, rather than necessarily shows I love, so some are a little 'safe'. Much as I'd have loved to do crazy sci-fi adventures or something, that might've been a step too far!

So I only picked American shows, and some are based more on research than actually watching them.
