So here's chapter 3:

PHOEBE: Cole! What the hell are you doing here? Since when are you alive...again?
COLE: You should know that I'd straight come to you at first, so now you have one guess since when I'm back.
PHOEBE: But...how?
COLE: Weird story, I got reanimated by some girl. PHOEBE: (more talking to herself) Oh that was the one that called.
PIPER: Just some girl? Tell us more! COLE: Well, actually, I think I'm not allowed to tell somebody about her, especially not you!
PAIGE: Why's that?
COLE: Because when I do that, she'll send me back to hell. I've been there the last 2 years, believe me, I don't wanna go back there so soon.
PIPER: Well, if she doesn't do it, we'll so it! So what's the difference?
COLE: I'm technically still invincible, she's the only one able to kill me.
PHOEBE:Unfortunately.
COLE: And I love you too, darling.
(Phoebe glares at him)
PHOEBE: Don't even think we could get together. For me you're still dead. That can't be changed only because some strange girl, we know nothing about by the way, brought you back. And we'll see if u really are invincible. (she's going upstairs)
PAIGE: Where are you going?
PHOEBE: To the book of shadows, have to look something up. Good Night (Cole is smiling, Phoebe sees it) Not to you!
(She's now upstairs, the other ones are still in the Manor, just standing there and don't know what to talk about)
PAIGE: So...I guess we're finished, I go to bed again. (She orbs away)
PIPER: You know Cole, I know that you haven't been alive for a long time, but there are still some groundrules. And I think I remember one of those was not to stay at some house at night, when you're not invited.
COLE: It's fine, I was just about to leave. So see you tomorrow (he shimmers out)
PIPER: Oh god, I hope not. (to Leo) So honey, how about we also go back to sleep? You know we have plans for tomorrow, so some sleep wouldn't hurt. On the attic, Phoebe is looking in the book of shadows
PHOEBE: There MUST be something to help us killing him again! Why can't he just stay away forever one time. Always the same trouble with him.
The next day, in the kitchen. Paige enters, Leo and Piper are already there
PAIGE: Morning!
PIPER and LEO: Hi. PIPER: Did you sleep well last night?
PAIGE: No, I wasn't able to go back to sleep, I was thinking about Cole the whole time. Poor Phoebe, she finally managed living without him, and now that.
PIPER: Yea I know. But, honestly, it doesn't really worry me that Cole is back, I mean, it isn't the first time, but what about that girl he mentioned yesterday? PAIGE: She must be really powerful.
PIPER: And we know nothing about her. Not even if she's just another demon, and easy to vanquish, or real trouble for us. I mean, she called us last night, which demon knows how to use the phone?
PAIGE: Cole.
PIPER: Yea, and that's the problem, all the demons we faced, the ones who weren't easy to vanquish were all living in our world, just akting to people normal people.
PAIGE: Yea, putting Cole to death wasn't really easy.
PIPER: And not only Cole. There were some others before your time, like Hannah and Rex. (Phoebe, looking tired, enters the kitchen)
PIPER: Morning Phoebz. PHOEBE: Morning.
PAIGE: So did you find anything in the book of shadows?
PHOEBE: Well, not really. You know, I didn't had a lot to look under, we have no idea what we are dealing with. And even the reanimating-part didn't help a lot. The ones who reanimate most are mainly alchimists, but I have my doubts she is one. They normally don't have a lot of contact to the rest of the world. She wouldn't have called, the would've simply sent Cole here, if she really was an alchimist.
PIPER: So who else would be able to reanimate someone? PHOEBE: Well, I really don't know. But I found out that this is really a strong power, mostly demons who don't have powerslike throwing eneryballs around have it. But that doesn't mean thex are easy to vanquish. There was this one bad witch with only one power. All the good witches thought it would not be necesarry to kill here. But then, one day, she created an army for here, she reanimated all the glorious warriors of all centuries, plus the demons who once led the underworld. It wasn't a piece of candy for the good witches to kill her again, with all the people protecting her, she was nearly invincible.
PAIGE: So how did they kill her? Potion? Spell? Both?
PHOEBE: No. They weren't able to kill her. Their luck was that she did a mistake. She was way too self-confident. She really thought she became too powerful to the good witches, and she forgot that the warriors were the ones making her strong. So more and more she started killing them herself, she was tired of them, she started killing them for the smallest mistakes. She was too self-absorbed, and then, one day, there was just a small army left. That was the opportunity for the good witches to attack them. They were all working together, around 10 good witches, they first killed a lot of her warriors, then they killed her with an athame. Her death made the left warriors disappear with her.
PIPER: Well, at least we know how to get rid of Cole. PAIGE: But only if this case is similar to the one Phoebe just told us about. I still think we can't rule out that she's a demon, and not a bad witch. So when did that happen, the story with the bad witch?
PHOEBE: 1806. So I think we can rule out that it's her. I remember her voice on the phone, she sounded really young, not older than 20.
PIPER: So you think it might be possible that they are related? PHOEBE: Might be possible. I think I remeber reading that she had a daughter, PAIGE: So maybe that daughter had another daughter, and she had another daughter, and so on.
PHOEBE: Would be good for us. That way we would at least know somethign about her.
PAIGE: yea, that she's nearly invincible, especially with Cole on her side.
PIPER: Don't be so pessimistic, that doesn't bring anyone any good.
PAIGE: So what do you think we should do?
PHOEBE: Well, I think there isn't much we can do. I think we just have to wait.
PAIGE: Just do nothing?
PHOEBE: Unless you have a better idea.
PAIGE: Unfortunately, no.
PHOEBE: So lets just wait, I have this feeling that sooner or later we will know who reanimated Cole.
PIPER: So enough of the demon-talk. I think it's time to get ready for our meeting with Joanna and her family.
PAIGE: Guys, just an idea, do you think it could be that daughter of Joanna, this Melina. I mean, yesterday you told us there is something about her, having to do with magic.
PHOEBE: I don't think so. I think she has some kind of telepathic power, that wouldn't help her reanimating her. And also, if it was here, wouldn't that make Joanna a bad witch. And I just don't that would be possible, we know here since forever.
PIPER: Well, Joanna didn't have to be a bad witch. Melina is just her stepdaughter, remember? I don't wanna say that Melina is a bad witch, only because she got some sort of delepathic power. But her age would fit, and it's strange that this started when she appeard. So we should keep an eye on her.

That was chapter 3, pls review again.
