"I wasn't aware you had anything to do with my creation," says Morgan in a deadpan. "Do you have a parental name you'd like me to use, or should I switch between mom and dad on whim?"
Giggle. "Switching's fine. And that might make matters awkward when it comes to you being my legal guardian."
Snort. "Not in front of people, then. If they knew they might try to force you to make more of me, and we can't have that. I wouldn't be original anymore."
"It's not all that bad. Though I've never been a mom before, so uh. Good luck!"
"Sorry, it was funny. In all seriousness, I will try to be a decent mother, if you do in fact want me to actually mother you."
"Um. I don't think we are actually close enough for that to be a reasonable dynamic, not to mention the fact that you look barely older than myself."
"Yeah, that's about my thoughts. Legal guardian that wants to make sure you don't spontaneously catch on fire or get bullied by people that think that until you are eighteen you are property, no actual mothering. But if you wanted it, I would try." Shrug.
