"Oh I've missed this," says Jack as the four continue to run towards the ambush. Holly's still holding the Doctor's warm hand as Jack is running faster to help the man who the aliens were after.

"Bet you have after one hundred years!" Holly shouts over the loud noise. Holly watches as Jack gets out his gun, making Holly gasp. She looks at the Doctor who also has fear in his eyes. Before Jack could shoot, the Doctor yells.

"Jack, don't you dare!"

Holly says at the same time, "no!"

Jack fires in the air. Holly panics and hides behind the Doctor as she tries to look where the bullets were landing. Thankfully, not far from them.

It's fine. It wasn't going to hurt you, transmits the Doctor, making Holly feel a little better. She breathes heavily from running, letting go of the Doctor's hand. Martha comes over to her and puts a hand on her shoulder to help calm down.

"And you do this all the time," whispers Holly. Martha nods.

"What are they?" Martha asks the man who Jack saved.

"There's more of them. We've got to keep going."

"I've got a ship nearby. It's safe. It's not far, it's over there," the Doctor points out as they're ready to start running.

"That's all you're worried about?" Holly asks, making him roll his eyes as she looks to see the tribe making their way towards them. She lets out a tiny scream.

"Or maybe not," says the Doctor.

"We're close to the silo. If we get to the silo, then we're safe," says the man they were helping.

"Silo?" The Doctor repeats.

"Silo," Jack says.

"Silo for me."

"Definitely," Holly says as she follows the group.

Martha wraps her arm around Holly's as the gate closes behind them. Martha can tell how scared Holly was, so she comforted her. Holly was thankful. She closed her mouth after showing the people her teeth to show that she was human. Holly got scared by that, because she knew there would be people with vampire-like teeth.

Inside, Holly stands near Martha, their arms unlinked. Holly listens as the Doctor is trying to tell them about the TARDIS.

"This is going to be difficult to write down in my journal," Holly murmurs to Martha. "I'm supposed to write down everything that's going to happen."

"It will be difficult, but I'm sure you'll be fine. We'll all be fine in the end. Eventually," says Martha. Suddenly, a little boy comes out with a clipboard and paper asking what they needed. Holly's just as surprised as Martha was. They shared a look.

"Sorry, but how old are you?" Martha asks.

"Old enough to work. This way," the boy turns around. Holly lets out a snort and they start going.

Even though I laughed, it's horrible that they left a child to work for the people. He shouldn't be working at that young of an age, transmits Holly to the Doctor. The Doctor hums in agreement.

As they're walking, the boy asks for a woman the man they were helping was looking for.

"It's like a refugee camp," says Martha. Holly nods as they continue walking.

"Stinking," Jack comments. Then noticed the looks given. "Oh, sorry. No offense. Not you."

"Don't you see that? The ripe old smell of humans. You survived. Oh, you might have spent a million years evolving into clouds of gas, and another million as downloads, but you always revert to the same basic shape. The fundamental humans," says the Doctor. The boy continues to call for the woman's name as he doesn't care for what the Doctor's saying.

"End of the universe and here you are. Indomitable! That's the word. Indomitable! Ha!"

"Is there a Kistane Shafe Cane?" The boy says as they all stop.

"That's me," says Kistane Shafe Cane, standing up.

"Mother?" says the man they helped get there.

The two reunited. Holly finally caught man's name, which was Padra.

"It's not all bad news," Martha nudges Holly, seeing her state. Holly smiles.

"Yeah. I guess not."

A young man stands up and Jack shakes his hand. "Captain Jack Harkness. And who are you?"

"Stop it," says the Doctor looking at Jack as he has his glasses on. Holly giggles, earning her a look. "Give us a hand with this. It's half deadlocked. I need you to overwrite the code. Let's find out where we are."

You tell him to stop that all the time. Give the guy a break, thinks Holly. The Doctor rolls his eyes, ready to responds, but as the door opens he almost plummets down, but is grabbed by Jack.

"Gotcha," he says as Holly finishes panicking. She puts a hand on Martha's shoulder.

Oh my god, are you okay? she thinks towards him as he says thanks to Jack.

Fine. Before I almost fell, I just wanted to say that you haven't been here for long, he says. So how would you know if I've said that all the time? Your show is different from what we've been through. You know that.

Well I know Leila, Nate, Scarlett and Neil have been here, but I don't know how different it's been.

"— they're passengers," Holly finally hears the Doctor say out loud, replying to Martha.

"He said they were going to Utopia," Martha says.

"The perfect place. Hundred trillion years, it's the same old dream. You recognise those engines?"

"Nope. Whatever it is, it's not rocket science. But it's hot, though." Jack replies.

"Boiling. But if the universe is falling apart, what does Utopia mean?" The Doctor asks. They shut the door. An old man, not like the one that was Nathaniel's (Nate's) father that Holly met, came through another door, getting closer to the group.

"The Doctor?" The man looks at Holly first, then Jack, and the two point to the actual Doctor who stood beside her. Holly lets out a laugh. Jack chuckles along as they follow the Doctor and the man.

Never letting that one down either, she transmitted through the Doctor's mind.

"Chan welcome tho," says a blue alien as the four, and the old man, walk in. Holly gives the kindest smile, even though on the inside she's freaked out because this is the first time she's met an alien that looked like her.

"Don't be so tense," Martha whispers to her.

"Can't help it," she whispers back. "Thanks for trying to calm me down, though."

"Hello," Martha says, noticing the alien staring at them, "Who are you?"

"Chan Chantho tho," Chantho says. Holly notices how Chantho says half her name before the sentence and after.

"Captain Jack Harkness," he introduces himself.

"Stop it," says the Doctor once more. Holly and Jack roll their eyes at the same time.

"Let him go, Doctor. You're not his dad," she says.

"Yeah. Can't I say hello to anyone?"

"Chan I do not protest tho," Chantho says, making Holly smile.

"Maybe later, Blue. Thanks for defending me, Holly. So, what have we got here?" Jack says, moving around the place. Holly goes over near the Doctor.

"And all this feeds into the rocket?" The Doctor asks.

"Yeah, except without a stable footprint, you see, we're unable to achieve escape velocity. If only we could harmonize the five impact patterns and unify them, well, we might yet make it. What do you think, Doctor? Any ideas?" Asks the old man, looking for an answer. The Doctor doesn't know.

"Well, er, basically, sort of, not a clue."

Holly feels bad for the old man. All this time he was looking for help and the Doctor couldn't exactly give it.

"I'm not from around these parts. I've never seen a system like it. Sorry."

"No, no. I'm sorry. It's my fault. There's been so little help."

Over in the corner with chairs, a table and a drinks machine, Martha pulls a transparent container from Jack's backpack. It contains a hand. Holly screams, bumping into the Doctor. She touches his arm as he sits down, and she is forced down along with him. She then remembered how in the episode: the Christmas Invasion when he fought against a monster after just regenerating, forcing his hand to fall off. So this is where the mysterious hand got to? Thought Holly to herself as she finished screaming inside.

"Oh, my God. You've got a hand? A hand in a jar. A hand in a jar in your bag," Martha says, flipping out as much as Holly was.

"Jack!" says Holly as the Doctor recognizes the hand.

"I said I had a Doctor detector."

"Eugh," Holly moves away from the Doctor, disgusted.

"Chan is this a tradition amongst your people tho?"

"Not on my street. What do you mean, that's your hand? You've got both your hands, I can see them. Holly, tell me you can see them."

Martha and Holly look at the Doctor. She nods.

"Long story," says the Doctor, "I lost my hand Christmas Day, in a sword fight. I assume you know about that, Holly?"

Holly nods again.

"What?" Martha said in disbelief. "And you grew another hand?"

"Er, yeah. I did. Yeah. Hello," he waves his 'new' hand at the two women who stare at him. Holly's stunned. He sees she's still in disbelief as Martha was, so he took his hand and made her chin face him. Her cheeks turned bright red as he let go. She inched backwards, making him roll his eyes.

"Might I ask, what species are you?" asks the old man. Holly squirms in her spot.

"Time Lord, last of. Holly here is a Time Lady. The last one. Heard of them? Legend or anything? Not even a myth? Blimey, end of the universe is a bit humbling."

"You say that so calmly," whispers Holly, looking down. She still can't believe she's a time lady. It sounded so… professional. So alien.

"Chan it is said that I am the last of my species too tho."

"Sorry, what was your name?" says the Doctor. 'Chantho,' thinks Holly to the Doctor. Notice how she says half her name in the beginning and at the end of her sentence?

"My assistant and good friend, Chantho. A survivor of the Malmooth. This was their planet, Malcassairo, before we took refuge," the man said.

"The city outside, that was yours?" asks the Doctor.

"Chan the conglomeration died tho," Chantho says.

"Conglomeration. That's what I said."

"You're supposed to say sorry," says Jack, giving the Doctor a look. Holly slaps the Doctor's shoulder.

"Oh, yes. Sorry," he says after glaring at Holly.

"Chan most grateful tho."

"You grew another hand?" Martha says, looking at him.

"Hello, again. It's fine. Look, really, it's me," he waves his 'new' hand again. Holly takes it and examines it, feeling each finger with her own. He gives her a look before bending the tips of his fingers. She screeches playfully and lets go of it.

"All this time and you're still full of surprises," Martha says.

"Chan you are most unusual tho."

"I agree, Chantho," Holly smiles at the alien. Chantho smiles back.

"So what about those things outside? The Beastie Boys. What are they?" Jack asks the two.

"We call them the Futurekind, which is a myth in itself, but it's feared they are what we will become, unless we reach Utopia," says the man.

"And Utopia is?" The Doctor asks.

"What's Utopia?" says Holly at the same time.

"Oh, every human knows of Utopia. Where have you been?" the man asks, dumbfounded.

"Bit of a hermit," the Doctor said after getting up. Holly looks at him as Martha motions Holly to get up.

"A hermit with friends?"

"Hermits United. We meet up every ten years and swap stories about caves. It's good fun, for a hermit. So, er, Utopia?" the Doctor asks curiously.

The man shows them a display on the gravitational field navigation system.

"The call came from across the stars, over and over again. Come to Utopia. Originating from that point."

"Where is that?"

"Oh, it's far beyond the Condensate Wilderness, out towards the Wildlands and the Dark Matter reefs, calling us in. The last of the humans scattered across the night."

"What do you think's out there?" Holly asks.

"We can't know. A colony, a city, some sort of haven? The Science Foundation created the Utopia Project thousands of years ago to preserve mankind, to find a way of surviving beyond the collapse of reality itself. Now perhaps they found it. Perhaps not. But it's worth a look, don't you think?"

"Oh, yes," says the Doctor.

There was something odd about this man… The man stared off in the distance as the Doctor was talking, making Holly's insides squirm again.

"And the signal keeps modulating, so it's not automatic. That's a good sign someone's out there. And that's, oh, that's a navigation matrix. So you can fly without stars to guide you. Professor? Professor? Professor."

The Professor says, "I, er, ahem, right, that's enough talk. There's work to do. Now if you could leave, thank you."

"You all right?" the Doctor asks, concerned.

"Are you okay?" asks Holly, also concerned, even though she felt something suspicious about this Professor.

"Yes, I'm fine. And busy."

"Except that rocket's not going to fly, is it? This footprint mechanism thing, it's not working."

"We'll find a way," says the Professor.

"You're stuck on this planet. And you haven't told them, have you? That lot out there, they still think they're going to fly."

"Well, it's better to let them live in hope."

"Quite right, too. And I must say, Professor er, what was it?"

"Yana," says the Professor. Holly sighs in relief, finally knowing what the man's name was.

"Professor Yana. This new science is well beyond me, but all the same, a boost reversal circuit, in any time frame, must be a circuit which reverses the boost. So, I wonder, what would happen if I did this?"

The Doctor sonics the end of a cable and pulls. Power surges through the machines.

"Chan it's working tho!" Chantho says happily.

"But how did you do that?" Professor Yana says, dumbfounded.

"Oh, we've been chatting away, I forgot to tell you. I'm brilliant."

"Mhm sure," says Holly, making Martha chuckle.
