Previously...
The twins looked at each other, not sure what to do.
Mason smirked, "You can't do anything. Those chains and handcuffs restrict your magic."
"S***," He grumbled.
Star grinned, "Exactly. So... you're listening to us from now on. Come along, we have work to do. Important work."
"Fine," He scowled, following them to the lab.
"Well, Aurora, I have a question for you..." Stanford spoke up.
Aurora looked up at him, "Yes?"
"Well, obviously I want to run a few tests on both of you... and also asking you a bunch of questions. Would you allow me to do so?" Stanford asked.
Aurora nodded, "Yes, of course."
"Good. So... I have a lot of questions. I'll ask basic questions, and then more elaborate ones as we get to know each other," Stanford admitted, "as I'm sure that would be more comfortable than to be asked all these weird questions at once."
Aurora smiled, "Alright, ask away."
"Why don't you look 30? Who taught you magic? How long did it take you to learn magic? How does you power vary from your father's? What's your home like? What do you do in your spare time? Any hobbies? Have you reached your full magical potential? What colour is your magic? Can you leave Gravity Falls or Reverse Falls?" Stanford asked.
Aurora laughed, "Because I chose not to. Father did, of course. A few years. ... I don't exactly know. It's... organized and... green. I... mostly like to practice my magic and make dolls and stuffed animals out of thin air for poor kids. I also like to draw. My hobbies are probably makes dolls and stuffed animals. Not yet. A mixture of pink, green, yellow, blue, violet, orange and white. Yes, I can, but I prefer to stay nearby."
"Interesting. Do you think he could teach us magic?" Stanford asked.
He scowled, "Never."
"Never? Why not?" Stanford asked, confused.
He growled, "You hurt Will. I'm NEVER teaching someone who's evil."
"Yet, you were," Stanford pointed out.
He grabbed a syringe from the table, "That was nine years ago. Almost a decade ago. So, shut up. Shut up, or I'll stab you with the syringe."
"Fine. I'll try not to annoy you," Stanford backed, away.
Aurora smiled, "That's probably a good idea."
"Fine. I have some questions for you, as well," Stanford turned to look at him.
He sighed, "Fine. What are they?"
"... How'd you physically birth triplets? Can you ensure you have triplets again instead of another single child? Can we remake your body and its powers again? Is Aurora your first child? Do you actually have s3x before you get pregos or do you just do a spell? Can you get mabel pregos without a spell? What happens if we do the zodiac? What happens if we summon you but you don't show up? So you have to? Is it painful? How much older than Will are you? 10-100-1000 years? if our long is your short than it might be like a 5000 yr gap. What would you do to keep your Will and Dip safe? Would you stay here and be our slave? Is dipper the first human you've truly loved? What brought around your change of heart from 'raging party that will destroy the universe' to 'naw look at me with my boyfriend'? Why did you cast the spell to have the triplets if you didn't want them? Is there some ancient prophecy (like dipper dying or being corrupted) that you were trying to stop with an army of your own children? How are triangles born...?" Stanford asked.
He sighed, "That's a long story that I don't want to talk about. Yes. Yes. Yes... she is. Either, it doesn't matter. Yes. ... I don't want to talk about what would happen. Nothing, really. No. Not really. A few years, not many. 10 or so years, really. Not much of a difference. Even if you could hurt Will, he can't die. As for Dipper... it doesn't matter. He'll be reincarnated, and I'll know immediately. Never. No. ... I don't want to talk about that. ... I have my own reasons. Not yet. ... I'm not telling you about the birds and bees."
"Fair enough." Stanford sighed, "I don't want to know about the birds and the bees."
