That was anticlimactic. There was a flash, momma and dad looked dazed for a bit, then they were suddenly kissing and crying at the same time. I grabbed the Eye of Chronos with my magic and quickly left. I still wasn't entirely clear why it was so awful watching your parents mate, but I still knew it was a really bad idea. Besides even if Star was wrong they should be left alone anyway. I walked down the back hallway that led to the workshop with a smile on my face.
The Eye of Chronos was a pretty thing. A black clock made out of what looked like some kind of stone, but with a wooden face. There was a flat image of a golden hourglass in the middle of the clock, just like dad's cutie mark. The numbers were just holes cut out of the clock face, but behind them were twelve different lightly glowing jewels. It was really pretty. There were also a bunch of gears inside, and when used all that seemed to vanish and there was just a weird hole in universe or something. I stopped admiring it only when I came to the main control chamber.
Star was off to one side a big wooden box next to her, assembling whatever was in it. She was almost finished. It nearly looked like a pony now. I hopped in place, nearly losing my grip on the priceless artifact I was carrying. Right now it was just a silver vaguely pony shaped lump, but it was clear what it would be. I then remembered the very specific instructions I had been given what to do with the eye now that mom and dad didn't need it anymore. So I first made sure I was turned away, opened the heart of the Tardis, and threw it inside. She made it very clear it was more important to get it in there fast as possible rather than worry about damaging either. I then quickly sealed everything back up and waited.
"You're sure that's what she said to do?"
I nodded. "It wasn't Rosey either, but Empress Cosmos. I'm pretty sure even though I made the promise several thousand years in the future she'll still know if I don't keep my promise, and come back and punish me somehow."
Star shook her head, then laughed. "Dinky, I know you're smarter than me but sometimes you really don't think. Of course she'd know if something bad happened. She'd remember something went wrong and right after you make the promise already know if you kept it."
"Uh, time doesn't work like that. Not here."
"Oh whatever, you know time isn't my talent or anything. Still, you did it so don't worry. Besides no matter how scary you tried to make her sound or how powerful, Twilight is still the same dorky librarian at heart I'm sure."
"I guess. Now she said that once I do that the Tardis should…"
I didn't get to say the word change. I was beginning to suspect I knew exactly what I would see. I was dead wrong. There was no cobbled together mess of steam and magic in a futile attempt to get home, it was sleek, and bright, and full of clocks and windows. They looked in on various locations in Equestria, and beyond, across the full width and breadth of time. The walls were mostly white, but everything else bronze, and silver and hints of blue here and there. The console looked the least different, but the controls were modified, far fewer buttons, and far more levers and switches. It wasn't just resized, but designed for ponies.
"Uh, isn't she not supposed to be able to do that when we're in here?"
"I think so." Then I turned to Star and smiled "Ooo, I almost forgot. Are you done yet?"
"Almost." She smiled. "It has been a while, hasn't it? The strange thing is I think this version of Bluebird is even better. You just need to hook her up."
"I do?"
"Well I can't do it. I mean I'm a jeweler, and can follow instructions, but this super weird time lord tech, that's all you. It looks sorta simple I just can't understand her directions, but I bet you will. Mainly because it says it's for you."
She then held up a small page colored slightly differently from the rest and my name was indeed at the top. I think Star understood fine, just realized the Tardis would never let her open the panel in question. I grabbed the modified crystal with my magic, and quickly opened a panel that was thankfully still in the base of the console in the same place, and swapped out the crystals. Then I passed the crystal I just got from the Tardis to Star and she began installing it in the puppet's back.
"You do know she won't know you this time right?"
"Well she might a little, but I know. It's okay, her I like. Spending more time with her doesn't seem like a chore."
"But Star he's what makes momma happy the most and…"
She sighed. "I know. I know you're so amazing you really fixed the unfixable. Everything will be great from now on. I get it. I'll adjust."
"Uh…"
"Now, lets see what Bluebird thinks of your redecorating."
She closed it and with a little spark from her horn the connection was made. The Doctor never understood how swapping the crystals made the connection in the first place, but it sure worked somehow. Then the chameleon circuit came online and instead of a pale imitation of a pony was the dark blue mare I'd come to know fairly well. She looked the same too, right down to the slightly wild bright silver hairdo. Star and I both hugged her.
"What is going on. This makes no sense. I'm still, but at the same time…"
We both released her. "I never thought you'd be confused." Said Star
"I guess Blinkie's second brain thing must be really weird though."
"That makes sense." Added Star
"Second brain? So this body you somehow connected to my systems really does have a separate processor?"
I nodded. "Yea, but it's not totally separate. Mostly it's just for motion and stuff, allowing you to multitask better."
"But honestly we don't know. We do know that it somehow makes you more of a pony than you already are. Blinkie's tech is weird."
Bluebird nodded. "Oh yes, the sister of the Pink one who against all common sense can enter me without using the door, even when in transit. And even when she has been left in present day Ponyville."
Star and I both nodded.
"This is a very strange universe. I never thought I would get a chance to speak."
"So Bluebird, what do you think of what my adorable little…" began Star
"Bluebird? That is in reference to me, correct?"
I nodded. "Uh huh. I mean I guess we sorta named this body by accident cause we already knew it but the Doctor did it the first time."
"Yea. He's not very creative. The professor isn't much better apparently. When she hooked her Tardis up to something like this body she called him Pink Box."
"That is not a very good name." Then she blinked. "I have an opinion on that? I mean I've had opinions before but why did I waste a clock cycle even thinking about something so utterly trivial?"
Star smiled. "As time goes on you'll find you might as well be a pony. Well other than the not leaving bit, but you've never seemed to care."
"She means this body requires the interior of the Tardis to function."
"The very idea of leaving myself seems, strange."
Then she held up a hoof, then put it down. She then looked up, then down, then took a few steps. She was stiff but otherwise it was a normal enough gait.
"On the other hoof traveling about inside myself does as well but apparently it's the position I'm in. The idea of a body even stranger."
"Don't worry, I'm sure you'll get used to it. Now, since you have a convenient mouth again, how about you tell us what that thingamagig did."
"It integrated itself with my systems to both upgrade me instantly, and hide its presence. Magic is still well beyond my understanding, but not only was I able to detect it's presence due to the Doctor's modifications, but that ability is now greatly enhanced."
I then gave her lag a hug again. "You know, you don't just feel soft, but like a real pony. Blinkie really is amazing."
Bluebird smiled. "That feels nice." Then she blinked. "Wait."
"Oh, and you have emotions too." Said Star "Or at least simulated emotions."
"That's actually not as new as you think, but a great deal certainly is. This will take some getting used to."
I smiled. "But it's completely new and strange, so you love it right."
Then Bluebird laughed. I began to giggle. We were a family again. Everything would be perfect. Nothing could go wrong now.
