"Okay, whoa, obviously somebody needs a Midol!"
                                -Prue


    It would seem that Cole has fallen hard for the youngest Halliwell, because as he lies in bed awake, Phoebe lies next to him. She is wondering again about the secret he is hiding from her. She reassures him that whatever it is, he can share it with her. But as they both sit up, Cole returns to his demon form and attacks her.
    Suddenly Cole wakes up. It was all just a dream. But standing in his room is a member of the Triad. He is rather angry that Cole has failed in his previous tries to eliminate the Halliwell sisters. He explains, in a not so subtle way, that if Cole doesn't finish the job that he started, then he will be dead. It's kill or be killed now.
    Over at P3 the next night, the Halliwell sisters conference about the Triad and the evil agents that are after them. Prue, as always, seems the most concerned and tries hard to get her sisters' attention. But Phoebe is zoning, wondering why Cole is so late. Finally he shows up, but Prue refuses to let the subject drop. She wants all of them to practice their demon fighting. In order to continue the conversation she starts calling it an earthquake drill once Cole arrives. She wants to do the earthquake drill the next day. Piper has a doctor's appointment, but Prue persuades her to miss it. Phoebe needs Prue's car in order to get home from school for the drill and Prue reminds her once more to fill the gas tank before she returns it. But now Piper is worried about the home owners meeting at their house the next day. As Phoebe tries to talk to the flustered DA, Prue asks Phoebe if she can cover the meeting. Phoebe refuses, until Prue threatens to take the car back. Phoebe relents then turns back to Cole. But by now his mind is on other things. He has seen the sisters' Achilles Heal, their underlying frustration with each other. He will use it to drive them apart. He brushes off Phoebe, much to her disappointment, and quickly makes his exit.
    The next morning the girls are eating breakfast together. Phoebe tells her sisters that Cole is avoiding her. But Piper reminds her that Cole must really love her. Prue got that feeling from him when she was an empath.
    Their conversation is interrupted though when Belthazar bursts in. Phoebe lets loose with one of her levitating kicks and eventually Piper slashes him with a dagger, hoping to get some of his flesh for a spell. But as she does the demon disappears in a flash of white light and there stands Leo. Prue is happy with their practice and only has a few minor complaints. But Piper refuses to do it again. She wants to have a boyfriend left at the end of the day. As they get ready to go, Prue and Phoebe realize that neither of them can get the food for the homeowner's meeting. They both look to Piper. But once again, she has a doctor's appointment. Nobody seems to care though, and so she ends up with the job.
    Back at his apartment, Cole has summoned the demon Andras. He can use people's own anger against them, infecting them with rage. Cole wants him to break the bond between the Charmed Ones. Andras seems only too happy to oblige.
    Returning to the car after class, Phoebe finds Cole there waiting for her. He wants to have an early dinner with her. Phoebe is worried about bailing on Piper, but eventually agrees. As she gets ready to leave, Cole waves his hand, thereby messing with Prue's car and causing it to leak gasoline. Poor Phoebe is about to return a car with an empty tank yet again.
    At the manor, Piper is anxiously trying to cook more food for her ornery guests. Prue comes and goes as Piper tries to survive the neighbors' constant bickering. Just then she spots Phoebe. Her younger sister begs her to take over the meeting so that she can go out with Cole. She wants to talk to him about where the relationship is going. Once again, Piper agrees to do something someone else should have done. Phoebe disappears up the stairs to get ready and Piper enlists Leo's help. But then he is called away. Piper is none too happy about getting left alone and she glances over at the neighbors with serious contempt.
    Not long after, Piper is still trying to mediate between the bickering people in her living room. Phoebe waves good-bye and Piper realizes that her sister is wearing her earrings. But its too late to catch her. Just then Andras appears at the window. He sees Piper struggling to get control of the situation and throws something resembling a dark cloud at her, thus infecting her with some serious rage. Piper turns on the neighbors and after throwing her food at them, she finally sends them packing.
    Phoebe and Cole sit in some nice club somewhere, discussing their pasts. Phoebe tells him about her childhood and her mother's death. As she talks, Cole begins to see how much her sisters mean to her. He, on the other hand, will not say much about his past. Apparently he lost his family when he was young.
    Prue returns home, her cell phone glued to her ear as she tries to explain to her boss why she didn't make the photo shoot. Apparently her car ran out of gas. As soon as she tells him that the shoot will be at P3 the next day, Piper takes the phone from her and hangs up on him. Prue is stunned and rather angry, but certainly not as angry as Piper. But all that is about to change.
    Piper tosses Prue's camera lens onto the floor just as Andras arrives to infect Prue. Piper's Cuisinart flies as Prue smashes it onto the ground. Both of them glare at each other.
    Outside, Phoebe kisses Cole, then says good-bye. Upon entering the house, she is rather confused by her sisters' behavior. Both of them turn their attack on her. Prue's mad that her car had no gas and Piper's angry that the world seems to revolve around Phoebe. Unfortunately for the trio, Andras next manages to infect Phoebe with rage. She quickly lets loose on her sisters and pretty soon things have gotten out of hand. Piper accuses Phoebe of never amounting to anything. Phoebe accuses Piper of being too big of a baby to ever leave for college. And Prue is sick of having to take care of them both.
    The last straw is when Piper steals back her earring. Phoebe attempts one of her flying kicks on her sister, but Piper pushes her back into Prue. Phoebe then throws Prue's camera, which Prue deflects back towards her. Phoebe levitates and the camera nearly hits Piper. But Piper manages to freeze it. Still within seconds it has unfrozen and smashed into the wall. The sisters stare at each other for a moment and then Phoebe runs out of the house. Up in the attic, the triquatra, the symbol on the front cover of the Book of Shadows, separates into three different pieces. 
    Later on that night, Piper helps Prue clean up  their mess. Leo arrives wondering what happened. Even the whitelighers felt the disturbance. As they talk, Prue and Phoebe realize their powers are gone. Leo explains that when they used their powers against each other it severed the power of three. They are totally vulnerable now.
    Phoebe arrives at Cole's teary eyed, still upset over the fight. He reluctantly lets her in as she starts to tell him what happened.
    Back at the manor, Prue, Piper and Leo find Andras in the book. As they read over his description, they come to realize that it was their own anger that allowed him to work his magic on them. Their resentment towards each other was part of the problem.
    As Phoebe continues to tell Cole what happened, Cole wanders over to a corner and grabs a dagger. He hides it in his waist belt as he sits down next to Phoebe. They start to kiss and he pulls it out, poised to kill her. But he cannot. He hides the knife again, then pulls away, telling her to return to her sisters, to figure out what happened between them. Phoebe finally leaves, but not before Andras sees her kiss Cole good-bye. The demon threatens to turn Cole in. But when Cole transforms into Belthazar, Andras decides to posses him instead and go after the sisters himself.
    Meanwhile, Prue and Piper start to worry when they cannot find Phoebe. Piper is upset as she remembers their mom, and realizes that early deaths seem to run in their family. But then Phoebe returns. Prue and Piper quickly explain what has happened, how they managed to lose their powers. Leo reminds them that they must restore their bond. So as he leaves they warily glance at one another. Finally Piper starts off the apologies and pretty soon they all seem to be on good terms once again.
    But then of course the possessed demon shows to break up the party. They frantically try to use their powers, only to realize that they still are not working. Prue urges her sisters to leave, but Piper and Phoebe agree to stick by her. It is then that the triquatra returns to its normal state. The power of three has been restored. They quickly kick some demon butt, knocking Andras right out of Belthazar. The girls watch in amazement as the demonic DA kills Andras then turns on them. Piper manages to use his dagger against him, thereby getting a piece of his flesh. But he tosses her to the ground just before Prue tosses him out the window. Just out of their sight, Belthazar transforms back into Cole, then disappears.
    At P3 later on, the sisters sit once again. They all agree that they should communicate more, instead of bottling up their anger. Phoebe mentions that the neighbors managed to work things out after Piper's interesting mediation techniques. She even goes so far as to suggest that Piper take all of the meetings. But Piper quickly refuses. She's gotten a lot better at saying no in the last couple days. Meanwhile, Phoebe still puzzles over Cole. She vows to figure him out.
    Unfortunately for Cole, he has been called back by a very angry Triad. They realize that he squandered the perfect opportunity to destroy the Charmed Ones. And now they are going to destroy him. But with the dagger and a little quick work, Cole manages to kill all of them, before letting loose with an agonizing screams.
