Exiled from the Manor and hiding at Phoebe's, the Charmed Ones are contacted by two demons who help them prepare for the battle against the Triad and the Jenkins sisters.
Tropes
- And Then What?: After seeing how the Hollow affects Billie and Christy, Dumain makes this argument to the Triad. He says the girls may yet defeat the Charmed Ones this way, but he warns the Hollow will never leave them and that they'll go on an uncontrollable rampage that may even pose a threat to the Triad.
- Balance of Good and Evil: Nomed states that the Triad is evil incarnate; as such, they keep coming back because evil never really dies. Zohar reasons that the added power boost of the Hollow could possibly solve this problem.
- Beam-O-War: The Charmed Ones and the Jenkins sisters, all possessed by the Hollow, use them during the final battle. Oddly, the Charmed Ones fire six beams while the Jenkins sisters fire four, yet somehow the beams all still block each other.
- Big Brother Instinct: When Dumain shows up at Victor's apartment Wyatt reacts by orbing to Chris' playpen and putting up his orb shield to protect them both.
- Black Eyes of Evil: The Charmed Ones and the Jenkins sisters each get these when they absorb the Hollow.
- Blood Knight: Piper is chomping at the bit to take on the Jenkins sisters.
- The Bus Came Back: The only upside to what happens in the Darkest Hour: the Angel of Destiny brings Leo back.
- Call-Back: The way Piper cradles Phoebe's dead body in her arms is very similar to how Prue did the same to Piper herself in "All Hell Breaks Loose" - another episode where a sister's death is solved with going back in time.
- Continuity Nod: The Hollow returns, and Paige references how it drove the Source insane.
- Cross-Referenced Titles: With Kill Billie Vol. 1. This is the last episode where the Jenkins sisters are prominently featured as antagonists (they are Out of Focus in the next episode) . Kill Billie Vol. 1 was the episode where the story arc of their reunion began.
- Darkest Hour: After the battle has been fought and the Manor exploded, Piper wakes up to find out that Phoebe is dead, Paige is nowhere to be found (presumably dead as well) and the only other survivor is Billie. Piper starts beating her up and tries to kill her twice before Leo stops her.
- Downer Ending: See Darkest Hour.
- End of an Age: Nomed and Zohar's motivation is ensuring this. The Triad's continued existence is the only thing preventing the newer, less powerful generation from finally rising up and developing.
- Enemy Mine: The Charmed Ones willingly work with demons in order to come up with a way to stop Billie and Christy.
- Even Evil Has Standards: Dumain urges the Triad to reconsider summoning the Hollow, citing how dangerous and unpredictable it can be for good and evil alike.
- Foreshadowing: Victor telling Coop that only the heartbroken can truly understand love sets up Phoebe later sending Coop away.
- Godzilla Threshold: After the first fight ends in a draw, the Triad wants to give the Jenkins sisters an edge by summoning the Hollow and using its absorption abilities to claim Wyatt's powers.
- Hair Reboot: Inverted. Leo's hair is inexplicably shorter than it was when he was taken - despite him literally being frozen in time.
- Hoist by His Own Petard: The Triad want the Hollow summoned in order for the Jenkins sisters to achieve the power needed to win. Nomed and Zohar overhear this and tell the Charmed Ones, at which Piper thinks it's actually a very good idea. As a result, the Hollow gets split among both teams of sisters. The Charmed Ones even end up taking out the Triad before facing the Jenkins sisters.
- Hope Spot: After Leo is returned, Piper hears a noise in the wreckage and hopes that it's Paige. Instead, it's Billie.
- No-Holds-Barred Beatdown: Piper delivers one to Billie after finding her among the wreckage instead of Paige. Leo's intervention is the only thing preventing Billie from being killed.
- Papa Wolf: Victor, not knowing that Coop is an ally, reacts to him beaming in by telling Wyatt to put up his shield to protect Chris and threatening to hit Coop with a poker. He also warns Coop that he won't let Phoebe be hurt falling in love with another magical being.
- Please Wake Up: Piper after finding Phoebe's body among the wreckage of the manor.
- Pragmatic Villainy: Nomed and Zohar help the Charmed Ones in order to prevent the Triad from taking power.
- Screw Destiny: The witches did this on accident. The Angel of Destiny says that the battle didn't occur how she had expected it.
- Screw This, I'm Outta Here: Dumain, as the Hollow-infected Jenkinses start glaring at him and attack. Nomed does similarly in regards to the infected Charmed Ones, albeit at Zohar's expense.
- Sdrawkcab Name: Nomed is a very obvious example.
- Skewed Priorities: The sisters keep focusing on stopping Billie and Christy. Nomed ultimately reminds them that that solves today's problem, but that it won't truly be over until the Triad is permanently vanquished.
- So Proud of You: Victor over Chris saving Wyatt.
- Spoiler Opening: Brian Krause reappears in the opening credits.
- Stock Sound Effects: The sound effect used when the Manor blows up is the same sound effect from Angel when the Angel Investigations office is blown up.
- This Cannot Be!: Chris manages to sense Wyatt and orb him out of the attic. As this happens after Wyatt's powers are drained, Dumain has this reaction.
- This Is Gonna Suck: When the demons offer to help them, Piper briefly sees Leo standing in the condo. She doesn't think it's a good omen.
- To Be Continued: How the episode ends.
- Trash the Set: In the final scene of the episode, the Manor is blown up. As a result, this episode was actually filmed last (as the Manor was still needed for "Forever Charmed").
- What Happened to the Mouse?:
- As we never see Paige's body, her death doesn't seem to be confirmed. However the next episode opens with Piper and Leo coming into Phoebe's condo, we can assume they did search for Paige and confirm her death.
- Nomed the demon disappears after the sisters absorb the Hollow's powers. Presumably he went off gathering power to one day challenge them or their descendants in the future.
- What Is This Thing You Call "Love"?: Victor is unimpressed by Coop's credentials, saying that no one (not even a Cupid) can truly know what love is until they've had their heart broken. Coop begins to understand when Phoebe sends him away.
- Would Hurt a Child: Christy will gladly use Wyatt to summon the Hollow. Billie is conflicted but goes along with the plan anyway.
