"You're a Charmed One, Piper, and you aren't living up to your true potential."
She furrowed her brow. "What do you mean? What potential? Other than being a witch, I mean."
He sighed. "You haven't read the second chapter of your Book Of Shadows, have you?"
She shook her head. "It always has the information we need, so it never occured to me to study it for it the sake of studying."
"Well, you are witches right?" She nodded. "And you know that, as the Charmed Ones, you have the combined magical power of several generations of powerful witches, right?" She nodded. "So why do you always need to resort to the Power of Three? That isn't the power of the Charmed Ones. That's just the power of three witches putting their magic together. Okay, so it works better for you three than any random witches off the street, but that would be the same for any three siblings who were witches, putting their magic together."
"So what are you saying? That we all need to get more powerful?"
"No, you see, witches have power that comes from within. Not like wiccas, who draw from the earth, or wizards who learn to force their will onto reality, You tap yourselves for your magic. And so many witches with a large amount of power must have enough self, literally, to channel the power. It's not a matter of gaining weight making you instantaneously more powerful. You still need either a source of magic, like inherited power or something enchanted, or lots of practice to build up the magic. But if a powerful witch tries to stay slim, her magic potential has nowhere to go, only a little trickle can be used. It's like pouring a gallon of water into a pint glass. The majority just spills. But if you have a bucket large enough, then the water fits perfectly."
"So being the most powerful witches in the world..."
"Would mean that if you want to use your full potential, at least one of you should become the fattest witch in the world, yes."
"The fattest witch in the...Hey, what do you mean 'one' of us? Won't we all need to?"
"Well, actually, like I said, the Power of Three can carry the magic of all three of you. So only one of you really needs to channel it, the other two just need to be there to supply their magic and chant. Of course II might be biased," Cole wrapped his arms around her from behind and kissed her neck. "But I think it should be you that gets to channel that much power."
"Well, why am I only hearing this now?" She asked. She was frowning as he rubbed her slender waist. She'd worked hard to stay slim, only to be told 'Stop it, I want you to be the fattest witch in the world!'
"Well, don't ask me. I've wanted you to gain weight since we started dating. The Elders, and that damn Whitelighter of yours, are the ones who are obsessed with observing the prophecies about the Charmed Ones. Of course, I didn't necessarily want you to develop your powers more, I just thought that you'd look really good, if you started gaining."
"Oh, well, that's just fantastic for you isn't it." She replied, sarcastically. The thought of not getting fat didn't even occur to her, since it might put innocents at risk. But she did wonder what her sisters were going to think. "I'm sorry, I'm just getting used to the idea. I suppose I should be grateful, not having to go to the gym anymore and being allowed to chocolate whenever I want to. And if you're serious about wanting to see me get fat for you, magic or not, I guess there's really not much reason for me to stay thin anyway." Her eyes widened. "Oh, and I've got all those clothes that are too big right now, but I guess I'll grow into them." She sighed. "And then right out again."
"Well, you know, gaining weight to serve innocents is probably grounds for a clothing growth spell. It's not personal gain if it helps the innocent indirectly." Cole smiled. "There are all sorts of loopholes to that 'Personal Gain' rule if you know what you're looking for."
"Well, what are you waiting for? Magic up some chocolate cake! It's for the greater good!"
Cole laughed. "That's my little piglet!"
"Little piglet?" Phoebe asked, sounding annoyed. But before he could apologise, she grinned. "I'm a pig, not a piglet. There's gonna be nothing 'little' about me!"
