Buffy prefers the way they flew last time. She’s currently a fish, being carried by a bird, who is Willow. She tells her friend that they’re flying under a disguise, trying to be sneaky as they travel. But the other sea gulls around them are bothering Buffy – she’s the one they’d eat after all. Willow thinks the disguise is extremely effective – natural looking, unlike, say, flying witches with Slayers for sidecars.

Buffy wants to be put down and starts flopping. The Willow bird lands and drops the fish, transforming them back to their normal forms and the witch is amused at Buffy’s mid transformation, half-human, half-fish look. Buffy is worried however – the local demons are searching for them and if Twilight finds them, she’s not really sure what they’re going to do.

Inside the safehouse, the separate Slayer squads are all together. Satsu and Kennedy have flown in from Tokyo. Willow has a mystical field to alert them to any approach. She has Wiccan Slayers backing her up. Buffy’s being weary about how much power Willow is using, but Willow assures her that she’s fine. Buffy addresses the girls: for now, the best thing they can do is disappear. But then Satsu asks a question: how long are they hiding for? What is their actual next step? No immediate answer is given.

In Berlin, Giles and Faith are in an underground bunker, hiding from the anti-Slayer public and keeping a low profile after the incident at Hanselstadt. Faith doesn’t like being underground. As they talk, the whole bunker begins to shake. Giles assures Faith that nothing natural can get through their ten-foot steel perimeter, but is proven wrong when large, troll-like demons smash through the closest wall! Faith yells that she knew living underground – closer to underground creatures – was a bad idea and, as Giles and his Slayer race out of the room to escape, they slam their weight behind the door, temporarily barring the demons’ path. It will not hold for long. Faith asks what they do now, to which Giles tells her to pray.

Elsewhere, in the darkness of the Catacombs of Rome, a group of Slayers and their Watcher Andrew, are investigating a disturbance that’s they’ve detected. They walk slowly, lanterns drawn, and find some ancient verse engraved on a wall. Andrew explains that it’s the prayers of Christian Martyrs and they come across a room. It’s filled with human skeletons and bones, all decorated into some kind of sigil. The Slayers are grossed out, but Andrew explains that this was their wish, their faith.

One of the Slayers hears a sound and asks if anything is supposed to be down there with them. Andrew tells her that he’ll go ahead and check. He walks towards the darkness, carefully, aware of every single noise. He hears something wet, squelching on the floor. As Andrew brings his torch up, he finds a foot, covered in blood, skin removed. He follows the foot up, across the creature’s chest, but Andrew already knows what he’s going to see. As the light hits the creature’s skinless face, Andrew gasps in shock and nearly drops his torch. “Warren.”

Before Andrew can call out, Warren shushes him. He tells his old friend that he’s dying: Amy has withdrawn her help in keeping him alive, and slowly and painfully, he’s falling apart. Before he dies, he’s come to Andrew, to make peace with his life and, hopefully, he says, patch things up between them. Andrew is horrified: Warren made him a killer! Warren tells him that he was misled as well: he thought they would be like Gods, as they always dreamed about. He knows what shame is now, and reckons Andrew must feel that too, especially since he’s hanging around with Public Enemy Number One, with the Slayers. He asks Andrew if he’s sure he’s on the right side. He is about to offer Andrew a proposal, but one of the Slayers suddenly bursts into the room. She’s flung aside by a large beast. She’s dead.

Warren yells at thin air – “Amy! You didn’t let me finish tricking him!” He vanishes in a flash of green light and the Slayers corral into the room, more demons at their backs. Andrew picks up the nearest bone, kills one demon by smashing it through his head, and then orders the girls to use the bones as weapons: he doubts the Christian Martyrs would mind.

In a cattle truck, heading across the European countryside, sit Faith and Giles. The truck isn’t pleasant and Faith makes Giles aware that she thinks so. He agrees, but at least, he says, they’re now on their way to Buffy.

Andrew and his Slayers return to their base in Rome. He needs to talk to Buffy.

In bed asleep, Kennedy and Willow cuddle for the first time in an age. Kennedy is startled as Willow gasps and suddenly sits up, wide awake. “I need to see Buffy.”

Soon, Willow, Kennedy, Xander and Dawn are outside Buffy’s room. They wait for her to call them in and Willow looks at her with alarm. “They found us. Everyone.” Buffy sits up and starts to move. “Who found us? Which everyone?” Willow explains that Twilight’s forces have struck at the same time: Andrew and his Slayers. Giles and Faith. And every demon in the country knows where they are.

Buffy orders Willow to use her magicks and bring their friends here, to safety. Within minutes, there’s reunions: Satsu updates Buffy on her Squad, all shop talk. Andrew greets a now-normal sized Dawn with a huge hug! Buffy hugs Giles, tears in her eyes. She tells him that she’s glad he’s back. He hugs her tighter and thanks her.

Xander and Willow gather everyone’s attention. They have mystical fields and weapons in place, and Wiccan Slayers working on shields, but the demons are gathering outside. Faith checks them out on a monitor. “Twilight found some evil-looking dudes to be his lap dogs.” Suddenly the monitors blink out – the demons have taken the cameras out. Now, they’re fighting blind.

Regrouping on the roof, the Scooby Gang can see the army approach. Buffy asks what all the stuff they have is, and Xander says that they have catapults and tanks. Is that it? They think they can do this with medieval weaponry? Willow calls back to her Wiccans to drop the bridge spell.

The bridge the army is travelling on suddenly vanishes, sending a small portion of the enemy into the water surrounding the safehouse. Xander is pleased: so much for their high tech approach, he reckons. Buffy asks him what they’re loading into the catapults.

Upon closer inspection, Xander, in horror, realises that the catapults are being filled with impact bombs, grenades and napalm! Buffy orders her group back away from the roof edges and a napalm bomb goes off, reducing many Slayers on the front lines to ash, completely blown away. Buffy is horrified. One of the Wiccan Slayers drops dead, a brain-fry, Willow confirms.

Satsu appears: she has a prisoner, but before anyone can move, Willow says she wants it, and teleports both herself and the prisoner away, leaving Giles confused. Buffy tells him not to worry – Will knows what she’s doing.

Within seconds, Willow is back – and she know how Twilight is tracking them: through their use of magick! While Giles disapproves of her executing the prisoner, Buffy orders everyone to the submarine! Andrew stops for a moment, big grin forming on his face: “We have a submarine?”

As the submarine moves away from Scotland for the last time, Buffy can try and relax for a minute. She’s away from the others, talking to Giles in her bunk. Giles is concerned about Willow’s power levels and her executing the demon. Buffy says she knows, but it’s what she had to do. Giles warns her that they’re going to lose her and Buffy wells up, telling him it’s way worse than that.

She tells him of her trip to the future and the battle with Dark Willow there. “What I’m doing now could be how she got that way, in the future.” Giles doesn’t know what to say, but they don’t have time to debate time-travel right now. Willow is using too much magic and Twilight is tracking them through magic – she clearly needs to stop anyway, which would surely negate the future Buffy saw. Buffy says that they know Willow better than that – there are layers underneath layers when it comes to magic and besides, their whole organisation has magical powers. They need the magic to fight back. She has an idea, a lightbulb moment. “Oh.”

Faith enters the room: the others are getting restless. They want to know where they’re going and what their next move is going to be. Buffy says that if Twilight is tracking them through their magic use then they need to go to someone who can suppress their magic so it can’t be detected. They need to hide it.

In a remote region, high above the rest of the world, glistening snow on high mountaintops reflect the dazzling light of the sun. Wild yak roam the fields, feeding on the land. A large structure, clearly oriental in some fashion, possibly Buddhist, stands tall, it’s gold and red architecture sparkling in the sun. A man sits, cross-legged, on the front porch.

A windchime blows, disturbing his meditation. He opens his eyes and sees that a giant nuclear submarine has suddenly appeared, out of nowhere, in his front garden. The meditation stops. The man gets up and peers at the submarine. Then he opens his mouth, in stoic surprise.

Oz‘s only reaction to the submarine is “Huh.”
