Hola! Welcome to the sequel of Fantastic Voyage, the next leg of the long journey for the Doctor and Alyssa.

Alyssa stared at the man wearing the Doctor's clothes as he ran around the console, flicking various switches. What the hell did I just witness? Who is this man in front of me? And what happened to the Doctor? He had said that he was going to change as he was dying but she never expected him to explode with that orangey light, leaving behind the unfamiliar man before her when the light faded, wearing the Doctor's clothes.

"6pm…Tuesday..." the newly regenerated Doctor muttered turning a knob "October... 2006... On the way to Barcelona!" the Doctor straightens up and faces Alyssa grinning as if he was pleased with himself. "Now then... what do I look like?" Alyssa just stared at him, unable to form any words in her shock "No, no no, no, no, no, no, no, no, no. No. Don't tell me" the Doctor checked himself over "Let's see... two legs, two arms, two hands..." the Doctor rotates his wrist "Slight weakness in the dorsal tubercle" his hands fly to his head "Hair! I'm not bald!" he said happily running his hands through it. "Oh, Oh! Big hair!" the Doctor touched his face "Sideburns, I've got sideburns! Or really bad skin. Little bit thinner..." the Doctor slaps his stomach "That's weird. Give me time, I'll get used to it. I…have got… a mole. I can feel it. Between my shoulder blades" he rotated his shoulder "love that mole!" the Doctor turned his attention back to the still shocked and slightly scared red head "go on then, tell me. What do you think?" he asked wanting to get her opinion.

"Who…who are you?" Alyssa managed to say quietly.

The Doctor was a bit confused by her tone. She sounded…scared. "I'm the Doctor", he replied.

Alyssa shook her head "No…where is he? Where's the Doctor?" her voice rose "what have you done to him?"

That confused the Doctor even more. He'd told her that he was going to change so he couldn't understand why she was acting that way. "You saw me, I, I changed…right in front of you", he reminded her gesturing to the spot where he'd regenerated.

"I saw him sort of explode, and then you replaced him, like a…a teleport or transmat or body swap or something", Alyssa said. Both her empath abilities and a small voice in her mind telling her that he was telling the truth. That she had seen him change but she was too caught up in this situation to take any notice to the voice or her empath abilities.

The Doctor stared at her in disbelief. She still wasn't accepting what she'd literally just witnessed only minutes ago. He had to get her to understand, no he needed her to understand that although he had changed, he was still the Doctor. "Ali it's me", he said softly, taking a step forward but she took a step back, still scared. "Honestly, it's me" he added trying to ignore the hurt he felt when she moved away. But he continued in his attempt to get her to understand, though he didn't take another step closer to her "I was dying. To save my own life I changed my body. Every single cell, but… it's still me"

"You can't be"

"Then how can I remember this? Our second trip I took you to the moon, 1969. Making you the first ever woman to set foot on the moon" seeing the look on her face, the Doctor continued "after our trip to Celaeno, you told me the significance of each of the charms on your bracelet" he gestured to it "you called it your 'bracelet of special memories'"

Alyssa's eyes widened as she finally realised that this was the Doctor. There was no way for him to know those things if he wasn't. Why didn't I take notice of my abilities? She thought mentally kicking herself for not taking any notice of them, they would've told her that he was telling her the truth. Though to be honest she was rather shocked over what had just happened that she wasn't really thinking clearly. At least not enough to consider listening to her abilities and the little voice inside her head, which had now changed its tune to 'I told you so' which she pointedly ignored. "Doctor", she breathed.

The Doctor smiled seeing that she now knew without a doubt it was him "Hello"

"I…I'm so sorry for how I acted, not believing you. My abilities where telling me that you were telling the truth but I didn't listen to them" Alyssa admitted "it's just…just a lot to take in".

"You don't need to apologise Ali. I know it is a lot to take in", the Doctor said. Although he was confused by her initial reaction, he now understood the reasoning behind it. He should've realised sooner that it was a lot for her to take in. The Doctor took a step back "so what do you think?" he asked, honestly wanting her opinion about this new him.

Alyssa looked him over, having not really done so earlier as she was too caught up in the shock of him changing right in front of her "it's different", she said.

"Good different or bad different?" the Doctor asked, hoping for the former.

"Good different without a doubt", Alyssa replied.

"Am I… ginger?" he asked seriously, really, really hoping he was. He'd always wanted to be ginger and out of all the bodies he's had so far, none of them had been ginger.

"No, I'm afraid you're a brunette", Alyssa answered.

"Aw I wanted to be ginger", the Doctor whined "I've never been ginger". It wasn't fair, Alyssa had lovely red hair while he was stuck with boring brown in this regeneration.

"Well…if it's any consolation, I think you still look good" that made the Doctor feel a little bit better even though he was a bit putout that he still wasn't ginger.

"Right!" he clapped his hands and dashed to the console "Barcelona. Dogs with no noses and lots of running guaranteed. We did lots of running didn't we? All across the universe" he flicked some switches "And that one time we had to hop", he added hopping on the spot.

"Yeah we did look rather ridiculous", Alyssa said with a laugh remembering that particular adventure.

"Oh and don't forget dancing" the Doctor went over to Alyssa, grabbed her hands and danced with her around the console room in a pseudo waltz. and spun her on the spot. She giggled when the Time Lord dipped her, getting a smile out of him.

"I wonder if you know more moves than you did before", Alyssa said as he pulled her back up.

"Let's find out", the Doctor said eagerly.

"But first we need music", Alyssa pointed out "Can't really dance without it".

"You're right Ali", the Doctor agreed. He dashed back over to the console and ran around it trying to find the controls to play music like he did last time after their trip to WW2. The Doctor stopped what he was doing when he felt rather strange all of a sudden.

"Are you ok?" Alyssa asked concerned by the look on his face.

"Yeah I'm f-" he broke off gagging.

"Doctor?" Alyssa asked.

He tried to talk but ended up gagging again a bit more violently this time "uh oh", he muttered.

"Whats is it?" Alyssa asked worriedly.

"The change is going a bit wrong", he replied before gagging again, falling to his knees. Alyssa crouched in front of him very, very concerned for him.

"Is there anything I can do?" she asked hating to see him this way. The Doctor opened his mouth to say something when a lever on the console caught his eye.

"I haven't used this one in years", he said jumping to his feet. He pulled the lever causing the TARDIS to shudder violently, nearly knocking him off his feet.

"What're you doing?!" Alyssa shouted as she fell backwards onto her bum.

"Putting on a bit of speed!" the Doctor said sounding crazed "That's it!"

With some effort, Alyssa managed to get to her feet. She grabbed onto the console and the Doctor ran around it turning knobs. "My beautiful ship!" the Time Lord shouted racing around flicking all the switches he could "Come on, faster! That's a girl!" he said urging his ship on. Alyssa stared at him slightly worried about the way he was acting and also being a little afraid of it too. "Faster! Wanna to break the time limit?!"

"Stop it!" Alyssa yelled at him just wanting him to calm down.

"Ah, don't be so dull Ali…where's your sense of adventure? Let's rip through that vortex!" he hollered not even noticing Alyssa making her way around to him. The Doctor felt a hand on his arm and glanced to his left at the red head. He found himself calming a little from her touch "The regeneration's going wrong. I can't stop myself", he admitted. The Doctor grimaced in pain "Ah, my head..." he groaned before he violently jerked away from her, turning crazed once more "Faster! Let's open those engines!" he shouted darting around the console to pull a random lever.

"What's that?" Alyssa asked as a bell started to ring.

"We're gonna crash land!" the Doctor replied laughing manically.

"Well then, do something Doctor!"

"Too late! Out of control!" the Doctor said, his voice rising hysterically "Oh, I love it! Hot dawg!" he hopped on the spot excitedly. Alyssa clung onto the console tightly terrified about what was going to happen. "Hold on tight, here we go!"
