I wake up on a cool, white couch. My head aches. The room is empty. I roll off the sofa and lunge for my wand that is on the table.

"Hello, Hermione." The third man from the woods is in an armchair directly opposite me.

"Stupefy!" He rockets backwards and through a window. He lies unconscious on the grass behind the house. I eye the broken window with amazement. Nothing human should have been able to do that. There were two layers of triple-glazing on that window. I jump out the window after him. "Now we're quits."

"Gee, Hermione, what did you do to Jasper?" asks Edward from behind me. He looks genuinely shocked.

"What he did to me. We are now evens. Now start talking or you can join your - what is he anyway? Brother? Team-mate? Lover? Friend? - regardless, talk, now." I look down at Jasper and nudge his body with my toe. He is rock solid. "Actually don't. I'll start summarising and you can tell me whether or not I am correct." He holds his hands up in a gesture of defeat.

"Go ahead."

EdwardPOV

She doesn't waste any time.

"Right. I knocked your brother for six. You are surprised by this. Obviously, that is not something I should have been able to do. Now, one questions why. When I met you in the woods, you appeared in microseconds. As did Carlisle, and Jasper. I heard none of you approach. Which means you are either very light - which you aren't - or you were virtually non-existent whilst you walked. I'm going with the latter. Jasper here lies at my feet rock-hard as though dead for several hours - rigor mortis. Now, I merely stunned him - and yet he appears not to be breathing. He also smashed through two layers of triple-glazed windows - and there is no blood. Nothing human should have been able to go through those windows. And when I put this between your eyes, you invited me to try and make it work on you. Which meant, that for some reason, you believed that it would not harm you. I have now proved otherwise. And I sense a power around you and your brother, like nothing I have ever felt before."

"So, then, what is your conclusion?"

"This," she says, holding out the stick, "works on every human, and once again, I remind you of your invitation."

"Yes."

"You aren't human."

"No."

"You aren't even alive." She is very calm. She meets my eyes.

"No, we are not."

"And if you are not alive, yet you are walking and talking, that leaves me with only one conclusion, Edward."

"And that is…"

"Vampires. You, Jasper on the floor there - Enervate - Carlisle, and however many more of you there are: you are all vampires. You are, in effect, the undead."

"And does that bother you?" Jasper asks. His voice trembles with rage.

"You got beat, Jazz, now live with it." He glares at me. I glare right back.

"Come on then. Does it bother you? Aren't you afraid I'll eat you?"

"No."

"What do you mean, no?"

"Hermione, allow me to intervene," I insert. Jasper looks like he may combust at any second. "You are somewhat threatening my brothers masculinity. First you knock him out. Then you tell him you aren't scared of him. Now, he finds this hard to deal with, seeing as it is, by tradition, impossible for a human to knock out a vampire."

"Oh, I'm not human," she says.

"Then what are you?"

"Oh please, boys, come on." She looks impatient. "I knock your brother out with a stick. I wear robes." She looks at us both.

JPOV

She actually rolls her eyes. I glower.

"I'm a witch, you bloody idiots," she snaps. "This is not a stick. This is a wand."

"That's impossible."

"Says the vampire."

"Look, the undead have been dotted through history for years - but it is impossible for you to be a witch. Magic isn't real."

"Says the boy who essentially is magic. Don't start rankling against things you don't understand or I will have to hex you into the middle of next week." She holds her wand flat on the palm of her hand and it starts spinning. She says nothing, but it pauses. It stops on first me, then Edward, then Alice's bedroom window, glowing a different colour each time. She nods to it, and seven golden sparks fly out of the end. It then stops spinning and becomes to all intents and purposes, just a stick again.

"And what was that?"

"There are seven of you, and three of you have some defining power."

"I suppose you've already figured out what those powers are?" Edward asks.

"Of course. You can read minds. The unseen third element can see the future. And you, Jasper, you shouldn't even exist and your power is something I have never, ever encountered before. You can sense the emotions of all those around you and you can change them, manipulate them. Prophecy and mind-reading, those they have in my world. But not emotion manipulating."

"Scared of me now?"

"No. Now, look, I know there are the other five of you watching me prove beyond doubt I have magic in my fingertips, and as that is very rude, them being able to see me, and me not being able to see them, why don't they join us?"

She doesn't seem even remotely fazed by being surrounded by vampires in less that a second. She doesn't even blink. She looks at Esme surveying the broken window.

"Oh, God, sorry. Here - if you would move out of the way Edward, I can fix that." She mutters under her breath again. She doesn't use the wand. "Reparo." The broken shards of glass fly up, realign themselves and fit back into the frame. Emmett surveys her.

"So you're a witch?"

"Yes, I am a witch. And this is the unseen third-element, the one who sees the future? Alice, right?"

"Um, hi."

"Ah, you didn't see me coming. I can explain that. I was never meant to come. I'm here quite by accident."

"Really? What kind of accident?"

"I fell through Reality itself. I'm not even supposed to be here - jumping through Reality isn't even meant to be possible."

"So how did you manage it?"

"Time-Turner. We - back in my world - can travel through time. But my Turner malfunctioned, and I tore a hole in the fabric of Reality itself. I fell through this hole, and it opened on the other side here, in this world. I'm not bothered by vampires - because we have them back home. I have to get back. And you have to help me."

"Why?"

"Because in fourteens days, the hole in Reality will heal itself, and I will be trapped here forever. Travel through Reality isn't meant to be possible, and when it does happen, there is a limit on how long the universe can last without collapsing when it's ripped. It's like a crack in glass, right? A piece of glass cracks, it weakens, and if the glass is left, it breaks. Same principle with the universe. Unless the hole is sealed, every single Reality will collapse. Not just my world, not just this world, but every Reality, every world - and nobody knows how many worlds there are."

We stare at each other. And then she swings round and stares at Emmett, with absolute terror and wonder on her face.

"Whoa, there, tiger. Easy," he says, backing up. "What's wrong?" When she doesn't answer, he looks around at the rest of us. "What's wrong with her."

"Emmett," Hermione whispers. "Don't move."

"But -"

"Don't move. I'm serious, Emmett, don't move so much as a millimetre. Stay absolutely still. I need you to trust me."

"I've only just met you."

"I know, I know. Please, I'm not going to hurt you."

"What are you going to do to him?" Rose demands. Hermione doesn't answer, instead merely running her wand, once, over Emmett.

"Who are you? No, I know. You're his mate. Well, this changes things," she murmurs the last, obviously forgetting we can hear her, so we ignore it. "I will not harm him."

"Talk to us, Hermione, that's my son."

"I have seen you before," she speaks directly to Emmett. "I have seen you before. I had a rucksack, my bag, I need it." Edward fetches her bag, and she kneels and rummages around. She produces a portrait far too large to have been inside that bag. "That's you, there."

And sure enough, there is Emmett. Looking exactly as he does now, in a portrait that moves, wearing robes.

"You're time," she whispers.
