The Doctor walked down the stairs in a white tux, a euphonium tucked under his arm, "River!" he shouted out the doors, as Star came skipping down the stairs wearing a short purple dress with a rainbow puffy skirt with silver straps crossing over her neck, it seemed at this regeneration seemed to love dressing up, "Careful!" the Doctor called to her as she hopped down the last step and she lost her footing slightly. It also seemed this her was a lot clumsier and uncoordinated than last time, "We'll see you later! Tell Marilyn she's too late, she'll have to use the biplane. Take care!" he headed to the console, not noticing Star waving to Amy who sat on the stairs.
"Do you do this every night?" Amy asked.
"Oh!" the Doctor spotted her, "Hello."
"You're trying to conceal euphonium guiltily. Has that ever been attempted before?"
"What?" he flushed at being caught out, "Oh this, oh yeah, it's just one of those um…euphoniums."
"Ok…so is THIS what you do at night when we're sleeping? Have extra adventures?"
"We don't sleep as much as you." Star reminded her, "We keep busy or else we'll die of boredom waiting for you and Rory to wake up."
"Doing what?" Amy continued, "Actually tell me for once. You're my friend, my best friend, so tell me what it is you do."
"Ok," the Doctor nodded, "We just helped out a possessed orchestra on a moon base, before that we prevented two supernovas, wrote a history of the Universe all in jokes, and did a bit of local work in Brixton. Lovely practice, very short staffed."
Star tilted her head, seeing Amy looked down to the floor, sad, "What's wrong?"
"We're such tiny parts of your life aren't we?" she sighed, getting up and walking over to them, "All the friends you make just flicker in and out. You must hardly notice us."
"Amy you are enormous parts of our lifes," the Doctor assured her, "And you are all I ever remember."
"Speaking of which…" She got back to what she wanted to say to them, "My life doesn't make any sense."
"We know."
"That's what I've been trying to talk to you about."
"We know."
"Like…when I first met you I didn't have parents. I never had parents. And then you did…whatever it was you did…and rebooted the Universe and, suddenly, I have parents. And I've always had parents. And I remember both lives in my head, both of them, in my head, at the same time."
"That's fine isn't it?" the Doctor frowned.
"But it shouldn't be." Amy countered, "Why is it fine?"
"Rory was a Roman for 2,000 years." Star pointed out.
"He says he hardly remembers it."
"But sometimes you'll catch him just staring…remembering…"
"There are things Amy, everyone's memory is a mess." The Doctor continued, "Life is a mess. Everyone's got memories of a holiday they've couldn't have been on, a party they never went to, or met someone for the first time and felt like they've known them all their lives. Time is being rewritten all around us every day. People think their memories are bad, but their memories are fine. The past is really like that."
"That's ridiculous." Amy remarked.
"I know!" Star grinned.
"Yeah, now you're starting to get it!" the Doctor smiled at her, "Put your hand here."
"What is it?" Amy eyed it, wondering over.
"TARDIS telepathic circuits."
She placed her hand on the console, "What do I do?"
"Nothing. Just relax." He looked at the monitor, "Your saddest ever memory was…at a fairground in 1994. Can you remember why?"
"No." she shook her head, before frowning in thought, "Hang on did I…did I drop an ice cream? That can't be my saddest memory."
"Remembering ice cream is always sad." Star stuck out her bottom lip as the TARDIS thumped.
"Did we just land?" Amy asked, "Where are we?"
"What happened after you dropped the ice cream?" the Doctor asked her.
"Nothing, I cried. No, no…hang on there was a lady…and she bought me another one."
"Oh, good for her. What did she look like?"
"She looked like she…she had a funny dress, a night dress, she had red hair. Doctor…I don't understand. Why are you doing this? What is the point?"
"What did the nice lady say to you?" Star questioned.
"Cheer up, have an ice cream." She replied.
"Amy, time and space is never ever going to make any kind of sense." The Doctor admitted, "A long time ago you got the best possible advice on how to deal with that. So! I suggest you go and give it!" he opened the door to reveal a fairground.
"Ok, ok, so I ask you a big important question about life and you're basically telling me to go and buy myself an ice cream."
"No Amy," he put an arm on her shoulder, "I'm telling you to go and buy the three of us ice creams. I love fairgrounds."
"I hate you." Amy muttered.
"No, you don't. Do you get scared on ghost trains? I get a bit scared so is it ok if I hold your hand?"
"You can hold my hand." Star reassured him. "But first. We get the ice creams. Then we get changed and wake Rory up. And THEN we have fun at the fairground!"
