At the end of the last chapter, Eleven and Clara were facing death by firing squad...
"Braveheart Clara" comforted Eleven as the distraught Clara cried out. He wished he could hug her, but his arms were still tied. He needed a hug badly too.
All of a sudden there was a noise behind them.
"Excellent" called out the Emperor, "You've caught the other two. They can also be killed."
"Your Excellency" replied one of the guards with Ten and Donna, "Before you do anything, they came to us voluntarily, and with no weapons. I think they should be given a chance to speak, as they claim they have important news for us, bad news."
"Ok, bring them to the front and let them speak."
Clara and Eleven watched as Ten and Donna walked to the front.
"So you two are also in Amplatan on a date?" asked the Emperor.
"Mister" replied Donna, "We are SO not on a date. What have the others been telling you?"
"Your excellency" interrupted Ten, "I believe your planet is under threat. High up in the sky there is an alien ship, which I think is planning to invade. That's the threat to you, not us. If you don't believe me, I suggest you send someone out to see for themselves."
"Go and search the skies" the Emperor instructed one of his courtiers, who left the room.
"I suspect", continued Ten "That the invaders are waiting for us to leave; they must recognise that the TARDIS is an alien spaceship, and fear its power. It's our ships that are currently preventing the invasion."
"And why should I believe you?"
"Because we can help you. I came here to warn you, if I was just on a mission to rescue the other Doctor and Clara, I wouldn't have walked in the main entrance, would I?"
Suddenly the courtier rushed in.
"It's true, your Excellency" he spoke, "There's a ship up there in the sky, it belongs to the Churru people."
"That's grave news" replied the Emperor, "They are a mighty, warrior people. We are in real danger. Untie those two, they are clearly not the enemy."
Eleven and Clara's hands were untied, and they passionately hugged each other.
"Oh Doctor!"
"My Clara!"
"I thought we were done for."
"You're safe now."
"Aren't they cute together" smiled Donna. "Such a lovely couple."
"Yes, the Doctor and his impossible girl" replied Ten with a grin. "We might get a word of thanks in a minute if we're lucky!"
"Of course, er sorry. Thanks, really grateful" replied Eleven. "But how do you remember the words Impossible Girl? You wiped your memories."
"I brought them back" replied Ten. "Seeing that they related to the previous time we travelled together, I wondered if they might be relevant to our current situation. It was easy enough to do, to upload them back from the TARDIS."
"Ah. Find anything interesting?"
"Nothing that seems connected to Amplatan." Ten then burst into grin. "So Clara, how did you enjoy Space Luna Park and the Tunnel of Love?"
"We never went" Clara scowled. "His stupid TARDIS developed a fault."
"Is that really the case" pondered Ten, "Or maybe your Doctor didn't want to go, perhaps, for whatever reason?"
"Oh, er, it was definitely a fault with the TARDIS" mumbled Eleven in reply.
"It's quite sad Clara" continued Ten, "The ageing process. It's like an old man losing the ability to drive, I guess Timelords in their old age lose the ability to control the TARDIS, to look after it properly. I wonder if anything else about the Doctor doesn't work as well as it used to?"
"Absolutely not! Everything about me is in tip top condition, especially, er I can't really say in polite company, but you know what I mean, er my er..."
Eleven's stammering while everyone else desperately tried not to laugh, was thankfully for him, interrupted by The Emperor.
"Have you quite finished with your domestic chit chat! Our planet is under threat, and if it is your spaceships that are scaring the Churru people off from attacking, then clearly you can't leave, as it is your presence that is protecting us."
"That's the clever thing, your Excellency" replied Ten. "Both I and the other Doctor have a TARDIS. We can fly off in one to investigate what the Churru people are up to, and leave the other one here as visible protection for your planet."
"Good idea Doctor" replied Eleven. "Plenty of room in my TARDIS for all of us."
"I don't think so old man, we'll use mine" replied Ten. "After all, what if your TARDIS doesn't work again. We can't have a repeat of the Space Luna Park incident, can we, eh Clara." Ten winked at Clara.
"Hard to argue against that logic, Chinboy" replied Clara with her arms folded, causing Eleven to huff and look a bit fed up.
"I can't take the risk" interrupted the Emperor. "After all why should I believe you, when we've only just met? The only way to guarantee that a TARDIS is left here for our protection, is for one of you Doctors to stay behind. You with the chin, you clearly aren't as good in controlling your TARDIS as the other Doctor, so you will stay here, the rest of you can go."
"Me? That's a massive slur against my TARDIS control, which is top notch. And what is it about the chin?" Eleven groaned.
"I can stay with you" suggested Clara.
"No, I need you outside, helping the other two" replied the Emperor. "He'll be well looked after in the guest quarters. He won't be able to leave, but the accommodation is quite comfortable. We look after our guests."
"Ok, your Excellency, we'll be off then" replied Ten. "We'll be back as soon as we've found out anything."
"Thank you."
"And Doctor" Ten continued, "I'm sorry, I'm so sorry you can't come with us."
And with that Ten, Donna and Clara exited the room, Clara waving back at a forlorn looking Eleven.
So Eleven and Clara survive, not a great surprise I guess :-)
