It didn't take them long to reach the first locked door where Riley quickly typed something into a keypad. "Fix the clamp on", he instructed to Imogen, who did so.

"What are you typing?" she questioned.

"Each door's trip code is the answer to a random question set by the crew", Riley replied "Nine tours back, we got drunk, thought them up. Reckoning was, if we're hijacked, we're the only ones who know all the answers".

"That's pretty smart", Imogen remarked.

"Yeah, it is. However, we only get one chance per door. Get it wrong, the whole system freezes", Riley continued.

"We better not get it wrong then", Imogen said. She watched him go over to a readout screen and read the first question aloud.

"'Date of SS Pentallian's first flight?' That's all right", he said happily, typing in the answer "go!" he ordered Imogen. She pressed the 'trigger' button on the clamp. It beeps a few times, the lights on top of the clamp turns green and the doors open.

"One down twenty eight more to go", Imogen stated, hauling the clamp off the door. The pair hurry through the door and onto the next one.

"Gen? Riley? How are you doing?" came the Doctor's voice over the intercom as they neared door 28.

"Area twenty nine, at the door to twenty eight", Imogen answered.

"You've gotta move faster" the Time Lord urged.

"We're doing our best", Imogen told him, putting the clamp onto the next door.

"'Find the next number in the sequence 313, 331,367…'" Riley trailed off "I-I don't know the answer".

"379", Imogen told him.

"Are you sure?" Riley questioned "we only get one chance".

"Just enter the number Riley" the Doctor called.

"Trust me, it's the right answer", Imogen added. Riley looked at her for a moment before putting in the number. The light on the clamp turned green for the second time and the door opened. "We're through", Imogen reported.

"Keep moving. Fast as you can" the Doctor said "And Gen, be careful. There may be something else on board this ship" he added in a quieter tone.

"Will do. And if I get any feelings, I'll let you know", Imogen said.

"That's all I ask" the Doctor said.

The brunette pulled the clamp off the door and followed Riley to the next door. She repeated her actions of putting the device onto the metal and waited for Riley to answer the question. "Riley? What's wrong?" she asked seeing him look rather distressed, head in his hands.

"This question is impossible", he mumbled.

Imogen moved over as far as she could all the while keeping her hands on the clamp "'Who had the most pre-download number ones, Elvis Presley or The Beatles?'" she read aloud "that's easy. It's Elvis".

Riley typed it in and a split second later the light on the clamp turned green, the door opening. "You weren't wrong about being able to help", the man remarked.

Imogen stiffened when she felt a familiar sensation come over her. This one had her rushing to the nearest intercom. "Doctor get to the medical bay now!" she ordered.

"A feeling?" the Time Lord asked.

"Yes, now go!" the brunette shouted before cutting off her connection.

"Why did you want him to go to the medical bay?" Riley questioned.

"Because your friend is about to be in some serious danger", Imogen answered "and before ask, I don't have time to explain now. However, I will do once we've got the auxiliaries back online and we're safely away from the sun. I realise this is a big ask considering that you barely know me but I need you to trust me, please".

Riley looked at the brunette. He could see in her eyes that she wanted him to trust her… that she needed him to trust her. "Ok", he said quietly.

Imogen gave him a small smile "Come on. We've got to get onto the next door", she said.

Riley nodded and they continued on. They'd just gotten through the door when the intercom crackled to life. "Gen, we got Abi out of the med bay", the Doctor reported making Imogen breath a sigh of relief.

"Good. That's good", the brunette said "we're about to go onto door 26".

"You've got to hurry. Time's not on our side", the Time Lord reminded her.

"I know. We'll get there before the time runs out, I promise", Imogen assured him. She turned to Riley "Onwards", she said.

The two of them quickly fell into a routine as they went from door to door. They were making pretty good progress, that is until they reached door 17. "Come on!" Riley exclaimed, hitting the terminal.

"You know that almost never helps", Imogen remarked "You should never use force, you'll only embarrass yourself", she added, repeating what she said to the Doctor after he kicked the console in frustration when they were stuck in the parallel earth.

"What do you suggest I do then?" Riley asked, rubbing his hand grumpily.

"Well, you could…" Imogen trailed off when they heard a bang behind them.

"Who's there?" Riley called. There was a second bang and they put their gear down to go investigate. They watched a figure emerge from the smoke, wearing a heavy duty space helmet. "Ashton, what are you doing?" Riley asked, having recognised him. Imogen on the other hand didn't need to have a 'feeling' to know that something was very wrong with the man.

Her fears were confirmed when he spoke in he very deep, sinister voice "Burn with me". Ashton raised his hand to lift up the eye shield when Imogen darted forward, grabbing his wrist.

"I don't think so matey boy", she said "neither of us are going to 'burn with you', you got that?" she got no response from Ashton "Now, we can help. All you have to do is tell us what you want".

Ashton still didn't respond. The pair looked stared at each other for several moments before the man suddenly pushed her. Imogen stumbled, falling onto her backside. She stared up at Ashton as he slowly lifted up his visor…

Riley had to turn away, shielding his eyes as the light grew too bright. He heard Imogen scream. Then it all went silent. Riley slowly turned back to see both Imogen and Aston on the floor. He went over to his friend first, his head dropping when he couldn't find a pulse. Riley moved onto Imogen and tentatively touched his wrist. Oh thank god he thought relieved when he could her pulse thrumming under his fingers, albeit a little erratically.

He dashed over to the comms "Doctor, something's happened to Imogen", Riley said quickly.

"What's happened?" the Doctor asked. Riley was about to answer when Imogen started screaming again. Upon hearing it, the Time Lord took off, Martha following close behind.

The Doctor skidded to a stop next to the violet eyed girl. He scanned her with his sonic and his twin hearts dropped when the results showed that whatever had been in habiting Korwin was now inside his impossible girl. "Doctor?" Imogen whimpered.

"I'm here", he said softly, taking her hand.

"It's alive", she whispered "the sun's alive" Imogen held out her other hand "Martha".

"I'm here too Gen", the black woman assured her, taking hold of her hand.

"You have to go with Riley and dump the fuel", Imogen instructed "it's the only way to stop the ship from falling into the sun".

Martha nodded and stood up "come on Riley", she said. As soon she and Riley were gone, the Doctor gathered Imogen into his arms, holding her against his chest.

"You hold on, do you hear me?" he ordered "you don't stop fighting".

"I-I won't", Imogen promised.

Minutes passed and the Doctor still held onto Imogen even though she was starting to shake violently. "You should go", she stammered "I don't want to hurt you". She could feel the sun's influence growing stronger and it was making her more terrified that she was going to hurt the Doctor.

"You won't", the Doctor assured her "and I would never leave you, no matter what".

Suddenly Imogen gasped, her entire body tensing up before she went limp in the Doctor's arms. The Time Lord quickly scanned her and breathed a sigh of relief when the device showed that her vitals were back to normal. Then the comms crackeled to life.

"Doctor we did it. The fuel is dumped and we're heading away from the sun" Martha reported happily "How's Gen?"

"She's alright. Thanks to both you and Riley", the Doctor said. He dropped a kiss onto Imogen's temple "I love you Gen", he murmured.
