Later, Amy, Jack and Rory were asleep on the floor as Avery went to sit beside Toby.

"I'm sorry about your mother. You miss her a lot," Avery told his son.

"Three years," Toby told him, "No word from you."

"Toby…" Avery began to say.

"You promised her. You promised you'd come home. And she believed you would, right up until the day she died," Toby told him, "What made you do it? What made you... turn pirate?"

"Get some sleep now," Avery told him as he didn't want to answer his son's question as he grabbed his coat and left the room.

A while later, in her half-sleep state, Amy heard the voice of the eye patched woman, "It's fine. You're doing fine. Just stay calm." Amy then opened her eyes and saw the same woman with the eye-patch that she saw at the orphanage. The panel then slid shut as Amy sat up but the panel had disappeared.

The Doctor and Rose were looking up at the stars on the deck of the ship when Avery joined them.

"It's not one star, it's two," the Doctor said as he pointed at a star in the night sky, "The dog star. Sirius. Binary system."

"And it's sixty trillion miles from Earth," Rose added.

"I use it to navigate the ocean," Avery told them.

"We've travelled far, like you," the Doctor told him, "For a very long time, I travelled alone till I found my wife, who was disguised as a human, which is what we do when we hide away from danger in times of need. Space can be very lonely. The greatest adventure is having someone share it with you."

"If we get out of this I'll take him back to England," Avery told him, "He can't stay with me. I'm not the father he needs."

"Who are you, Henry Avery? Respected naval officer, wife and child at home. How did you end up here, wandering the oceans with a band of rogues?" The Doctor asked him.

"I've set my course now. Nothing I can do to alter it," Avery told him.

"People stared at it for centuries and never knew," the Doctor told him, "Things can suddenly change, when you're least expecting."

"Yeah, I agree, Doctor," Rose said as the Doctor patted Avery as he and Rose left him.

The Doctor and Rose were standing quietly in the middle of the captain's cabin, kissing for a minute when Amy entered the room behind them with Jack.

"Doctor?" Amy said, interrupting both Gallifreyans as they were making out.

"Amy?!" The Doctor exclaimed.

"Jack?!" Rose exclaimed at the same time.

"We didn't know that we'd see you two making out," Jack explained.

"Sssh," the Doctor said as he began to feel something.

"I feel it too, Theta," Rose told him.

"What can you both see?" Amy asked them.

"Feels like something's out there, staring straight at us," the Doctor told both humans when there suddenly was a crash of thunder as the ship rocked.

"Man the sails!" Rose yelled as she and the Doctor ran from the room with Amy and Jack following them.

On the ship's wreck, it was raining hard as Avery held the rigging as Amy, Jack and Rory rushed topside.

"To the rigging, you dogs! Let go the sails. Avast ye!" Avery yelled as Amy, Jack and Rory headed for the hopes holding the mainsail while Avery worked on the foresail as the Doctor was at the wheel with Rose, "Put the bunt into the slack of the clews."

"I swear he's making half this stuff up," Amy muttered.

"No, he's not, Amy," Rose told her, "He's speaking in pirate slang."

"Sounds like he's making it up to me," Amy told the Time Lady.

"What we really need is some sort of phrase book," Rory told his wife.

"Toby! Find my coat. My compass is inside it, boy," Avery told his son before he went below deck, "Heave ho you bilge rats."

"'Rats' was all I could hear," Rory told Amy as Toby came back with Avery's coat and the crown rolled out along the deck. All they could do was watch as Toby looked at his father, hurt by the proof that he was a pirate. The Siren reached through the reflection on the crown and shot into the air above the ship. She sang and floated down to the deck, her hand reaching out for Toby.

"Don't let her take you!" Avery told his son as he was enthralled as he walked closer to the Siren with his hand out, "No!" Toby then touched the Siren and disappeared with a scream, "No!"

Amy held Rory back as he tried to reach the Siren. Rose snuck up behind her and threw the crown into the sea, causing the Siren to disappear.

"I'm sorry, I'm sorry!" Avery apologized.

"You couldn't give up the gold could you?" The Doctor asked him, "That's why you turned pirate! Your commission, your wife, your son. Just how much is that treasure worth to you man?"

At that moment, the main yardarm swung around and knocked Rory into the churning water, "Rory! Rory!" Amy yelled as she ran to the side, "I can't see him. Doctor, Rose, I'm going in!"

"He's drowning. You go in after him you'll drown too," Rose warned her, "There's only one thing that can save him now."

"What are you talking about?" Amy asked them.

"The siren," Jack realized, "We need the Siren if we want to save him."

"You're right, Jack," the Doctor said, "The siren, she wants him. We have to release her." He then headed for the water barrel.

"Doctor, no," Amy protested as he released the lid with his sonic screwdriver and released the Siren.

"He's drowning. Go find him!" Rose told the Siren before it dove into the water

"What did you do?" Amy asked both Gallifreyans and the ex-Time Agent.

"If he stays in there he'll die," the Doctor explained.

"She'll destroy him," Amy protested.

"That thing isn't just some ravenous hunter!" Jack explained, "It's intelligent. We can reason with it. And maybe, just maybe, they're still alive somewhere. We have to follow."

"Are the three of you mad?" Avery asked both Gallifreyans and the ex-Time Agent.

"If we ever want to see them again, we have to let the siren take us. We'll prick our fingers," the Doctor explained, "All agreed?" He then held out a fist, "Yeah?"

"Aye," Rose answered.

"Aye," Jack answered.

"Aye," Avery answered.

"Aye," Amy answered.

"Aye!" The Doctor answered before he pricked everyone's fingers and a black spot appeared on the palm of all five of them and they looked at them as the Siren appeared before them and began singing before they all reached out to her as they disappeared from the ship.

They then woke up on the floor of a spaceship.

"Where are we?" Amy asked.

"We haven't moved. We're in exactly the same place as before," Rose answered as they looked out the window and saw the pirate ship.

"We're on a ghost ship," Avery told them.

"No, it's real. Space ship trapped in a temporal rift,"the Doctor told them.

"How can two ships be in the same place?" Amy asked.

"Not the same. Two planes, two worlds, two cars parked in the same space," the Doctor explained, "There are lots of different universes nested inside each other. Now and again they collide and you can step from one to the other."

"OK, I think I understand," Amy told them.

"Good. 'Cause it's not like that at all. But if that helps," the Doctor told them.

"Thanks," Amy muttered.

"Amy, me and the Doctor have been to a parallel universe before," Rose told her before sniffing with tears falling down her eyes a little as she remembered the last time they went to another universe.

"Why's Rose crying a little?" Amy asked.

"The last time we went to a parallel universe, we lost her stepmother, Jackie Tyler," the Doctor explained, "She's not dead. We just can't see her as she's trapped in a universe where her husband was still alive after we went to the universe a few months beforehand, where her alternate counterpart was converted into a cyberman."

"Oh, Rose," Amy said as she went to comfort her, "I didn't know what happened to your stepmother."

"Thanks, Amy it was a few years ago before we rebooted the universe," Rose told her, "I was still 230 when we lost her for the first time and I was 232 and the Doctor was 903 when we lost her for the second and final time."

"All the reflections have suddenly become gateways," the Doctor added as he picked up a piece of metal from the floor and threw it through the window. It passes through and lands on the deck, "Ever look in a mirror and think you're seeing a whole other world? Well, this time it's not an illusion."

Then they heard a low beeping as they began to explore.

"The signal," Jack surmised.

"Yes," the Doctor answered.

"The distress call," Amy suggested.

"It is," Rose confirmed as they climbed the stairs that lead to the rest of the ship.

"There was a second ship here all the time," Amy realized as they heard the Siren singing.

"And the siren is on board," the Doctor added as he unlocked the door and it slid open to reveal the desiccated body of a pteranodon-like alien. Avery and Jack pulled out their guns but the Doctor and pushed their guns away, "Dead." The Doctor and Rose walked past the dead alien followed by Jack, Amy and Avery.

On the bridge, they saw another alien still at the controls. The Doctor walked up to it and saw that the view from the observation window was that of Avery's cabin.

"You both were right, there was something staring at us the whole time," Jack told both Gallifreyans.

"How long has this ship been marooned here?" Amy asked.

"Long enough for the Captain to have run out of grog," Avery answered.

"I don't understand. If this is the captain, then what's the siren?" Amy asked.

"Same as us. A stowaway," Rose answered as the Doctor used his sonic screwdriver to scan the body.

"She killed it?" Amy asked.

"Human bacteria," the Doctor answered as he checked the readings from his sonic screwdriver after he flicked it as it was extended.

"What?" Amy asked with confusion.

"A virus from our planet. Airborne, travelling through the portal," he said as hebput his sonic screwdriver away, "That's what killed it," he then leaned on the panel, "Didn't get its jabs," he then lifted his hand to show it covered in slime, "Urghhh! Look."

"What is it?" Amy asked.

"Sneeze! Alien bogies," the Doctor answered.

"Do you have to be that disgusting, Doctor?" Rose asked him as he shook his hand, trying to get the slime off and wiped it on Amy's coat as he walked past and left the room with Rose, Jack, Amy and Avery.

They enter a sickbay as the Doctor immediately began to scan the patients with his sonic screwdriver. Suspended from the ceiling were beds on which people are lying unconscious. They have breathing tubes attached to their throats.

"McGrath! He's one of my men," Avery said as he looked at McGrath.

"He's still breathing," Rose told him as Jack walked over to what looked like rectangular discs holding information.

"My entire crew is here," Avery said before he noticed his son and ran towards him, "Toby!"

"Rory!" Amy said as she ran to her husband as she noticed him.

"The TARDIS!" The Doctor yelled as he ran over to clear construction plastic and practically hugged it.

"Oh, brother," Rose muttered as she and Jack glanced at each other as they rolled their eyes.

"We have to get them out of here," Avery said.

"Wait!" The Doctor said as he scanned Toby with his sonic screwdriver, "His fever's gone."

"He looks so well," Amy said asRose, Jack and the Doctor then went over to Rory as Rose took out her sonic screwdriver.

"She's keeping him alive. His brain is still active but all its cellular activity is suspended," Rose explained as she turned over Rory's palm to show the spot, "It's not a curse. It's a tissue sample," she then showed one of the 'discs', "Why get samples of people you are about to kill?"

"Can either of the three of you help me get him up?" Amy asked the Doctor, Rose and Jack as the Doctor reached around to undo the tube as an alarm sounded and they heard the Siren singing.

"She's coming," the Doctor muttered as the five of them hid as the Siren arrived and approached Rory who was now awake, he tried to jerk away from her but she calmed him down as she continued to sing.

"Anaesthetic," the Doctor realized.

"Oh course," Rose said as she slapped her forehead, "Why didn't I think of that?"

"What?" Avery asked, confused about what they were talking about.

"What are you two talking about?" Jack asked.

"The music. The song. So she anaesthetises people and then puts their bodies in stasis," the Doctor explained as the Siren moved towards Toby with her hand resting just above him as Avery stepped out from hiding as he took his gun out as the Doctor whispered, "Avery," he then shouted, "No!" Avery fired at the Siren, causing her to turn on him, red and angry and hissed as she advanced on him as the Doctor ran to another part of the room to draw her attention and sneezed and the Siren stopped advancing on Avery as she heard the Time Lord sneeze and turned towards him with fire between her hands, "Whoa. Fire! That's new. What does fire do? Burn? Yes. Destroy? What else? Sterilise! I sneezed. I've brought germs in," he then pulled out a handkerchief and blew his nose then threw the cloth to the floor, causing her to shoot flames at the handkerchief, destroying it. With the distraction, Amy went over to Rory as the Siren moved slowly towards Amy.

"Amy, stop. Don't interfere. Don't touch him. Anaesthetic, tissue sample, screen, sterile working conditions. Ignore all the Doctor's previous theories!" Rose warned her.

"Yeah, well we stopped paying attention a while back," Amy told her.

"She's not a killer at all. She's a doctor!" The Doctor explained as Amy stepped back from Rory's bed as the Siren resumed her green glow, "This is an automated sick bay. It's teleporting everyone on board. The crew are dead and so the sick bay has had nothing to do. It's been looking after humanity whilst it's been idle. Look at her. A virtual doctor! Able to sterilise a whole room."

"Able to burn your face off," Amy asked them.

"She's just an interface," Rose explained, "Seeped through the join between the planes. Broadcast in our world."

"Rose is right, Amy," the Doctor said, agreeing with her, "Protean circuitry means she can change her form And become a human doctor for humans. Oh, sister, you are good!" Amy then reached for Rory again as the Siren turned red and hissed until Amy backed away.

"She won't let us take them," Avery noted as he stood by his son.

"She's keeping them alive but she doesn't know how to heal them," the Doctor explained.

"But why won't she let Amy near Rory?" Jack asked.

"Yeah, I'm his wife for God's sake! Why can't I touch him?" Amy asked, agreeing with Jack.

"Tell her Amy. Show her your ring," the Doctor said as he grabbed Amy's left hand, "She may be virtual but she's intelligent. You can't do anything without her consent. Come on! Sophisticated girl like you, that must be somewhere in your core program."

"Look He's very ill! OK, I just want to look after him. Why won't you let me near my husband!?" Amy demanded as the Siren held out her left hand as a ring of light appeared around it.

"Consent form," Rose explained, "You'll need to Sign it. Put your hand in the light. Rory's sick. You have to take full responsibility." Amy then puts her hand through the ring as the Siren disappeared as Amy, Rose, Jack and the Doctor rushed to free Rory as Amy turned off the power, causing Rory to jerk and gasp.

"He can't breathe, turn it back on," the Doctor ordered.

"What do we do?" Amy asked as she turned the power back on, "I can't just leave him here."

"We won't let that happen," Jack assured her.

"Of course we won't," Rose added as she agreed with Jack.

"He'll die if you take him out," Avery warned them.

"Rory? Wake up," Amy said, pleading with her husband as she stroked his face.

"Where am I?" Rory asked as he regained consciousness.

"You're in a hospital," the Doctor answered, "If you leave you might die."

"But if you don't you'll have to stay forever," Amy told him.

"You're saying that if I don't get up now…" Rory began to say.

"You can never leave," Amy finished.

"The siren will keep you safe," the Doctor told him.

"And if I come with you?" Rory asked them.

"You'd be drowning, on the point of death, Rory," Jack answered.

"I'm a nurse," Rory told them.

"What?" Amy asked, confused by what he was getting at.

"I can teach you how to save me," he explained to her.

"Hold on," Amy told him.

"I was drowning," Rory said, "You just have to resuscitate me."

"Just?" She asked him.

"You've seen them do it loads of times in films," he told her, "CPR. The kiss of life."

"Rory, this isn't a film, ok," she said, "What if I do it wrong?"

"You won't," he reassured her.

"OK, what if you don't come back to life? What if...?" Amy began to ask.

"I trust you," he told her.

"What about the Doctor, Rose or Jack? I mean why do I have to be the one?" She asked him, "Why do I have to save you?"

"Because I know you'll never give up," he explained before she nodded, knowing what he meant.

The Doctor and Rose then walked over to Avery, "We have to send this ship back into space. Imagine if the siren got ashore," he explained, "She would have to process every injured human."

"What about Toby?" Avery asked.

"I'm sorry. Typhoid fever," Rose answered, "Once he returns it's only a matter of time."

"What if I stay with him? Here. The siren will look after him. I can't go back to England. And what home does he have now, if not with me?" Avery asked them.

"Do you think you can sail this thing?" The Doctor asked him.

"Just point me to the atom accelerator," Avery answered, causing the Doctor to smile while Rose chuckled as the Doctor patted him on the back before he and Rose walked back over to Amy, Jack and Rory

"I know you can do this," Rory reassured her, "Of course if you muck it up I am going to be really cross. And dead."

"I'll see you in a minute," Amy replied as she looked at the Doctor, Rose and Jack who nodded as they hurried to unhook Rory from the life support system as he gasped for air. Together, the Doctor, Rose, Jack and Amy carried him to the TARDIS.

They then placed Rory on the floor just next to the door as Amy started to perform CPR on her husband, but had trouble doing it.

"I know you can do it, Amy," Rose told her.

"Rose is right, you can do it, Amy," Jack said, agreeing with the Time Lady.

"Come on, come on Rory. Not here. Not this way. Not today," the Doctor urged Amy.

"He trusted me," Amy told them, "He trusted me to save him."

"You still can. You can still do this. He believes in you," the Doctor told her, "Come on, Amy. Come on!"

"Please, please, please wake up, wake up, wake up," Amy begged her husband as she pressed harder on the compressions as she sobbed as she, Rose, Jack and the Doctor sat back from Rory's prone body. The Doctor reached a comforting hand over to rest on her back. Rory then started to sputter and cough up water. The Doctor stood up and looked down at the human couple in amazement.

"Amy. Amy, you did it, you did it!" Rory said as he hugged her as she continued to sob but this time with relief.

"She did it! Amy did it!" Rose said as she hugged her husband before kissing him.

A while later, Amy and Rory headed up the stairs from the console.

"I thought me and Rose were excellent pirates," Amy told Rory.

"I thought you were an excellent nurse," Rory told her.

"Easy tiger," she told him before turning to look at both Gallifreyans, "Goodnight, Doctor. Goodnight, Rose."

"Goodnight, Amelia," both the Doctor and Rose replied.

"You both only call me Amelia when either of you are worried about me," Amy told them.

"We always worry about you," Rose told her.

"Mutual," Amy muttered as she remembered the Doctor and Rose's next incarnation dying and then burning their bodies with gasoline.

"Go to bed, Pond," he told them before turning to Jack, who was standing at the top of the staircase, "You too, Captain."

"We can't tell them," Jack told Amy as he walked down the stairs to Amy and Rory, "It's their future."

"I know," Amy told him as the three humans looked at both Gallifreyans fiddling with the console with the Doctor fiddling with the monitor while Rose fiddled with the controls before Amy and Rory went upstairs to their bedroom and Jack went to his suite.

"Oh, Amelia," the Doctor muttered as he looked at the monitor as the TARDIS was still confused over Amy's pregnancy scan.

"What's wrong, Theta?" Rose asked as she walked over to him.

"It's Amy's pregnancy scan, Arkytior," he answered as he showed her the monitor.

"Something's going on," Rose told him.

"Yeah," he said, agreeing with her before kissing her, "And whatever it is, we'll find out real soon."

Please review.

Also should one of the Time Lords/Time Ladies that house had captured in the next episode be Rose's mother or any other of her relatives, causing her to start crying very hard and get angry and should I rewrite the minisodes Space and Time after the next episode?
