Note: I hope whoever requested this pairing on FFA is okay with my interpretation...Dr. Horrible's Lab
"Moist, it worked! She's really... real."
Moist ran into the lab - a lab he was rarely allowed inside, but today was a special day - and saw his friend holding a squalling baby girl.
"What did you do?"
"She's all I have left of Penny. Our daughter."
"But you and Penny never..."
"I took some of her DNA. The League had all kinds of plans for cloning people in their back rooms. I just took a few."
"Do they know about that?"
"They helped me figure out the genetic code to make her strong. I didn't figure out how to activate it, but I'm sure that will come later."Years Later
"Dad, I'm home!" Vi called.
"You're safe!" he blubbered, running into the room and throwing his arms around her.
"I'm better than safe," she said, returning the hug and squeezing a bit harder than she used to.
"You activated it," he breathed. "How?"
"Um... about that... I won't be following your footsteps in the League."
"I don't care about that. I just want to make sure you're okay; were you hurt?"
"Only a little bit. It turns out that the genetic code they gave you for me made me a Potential Slayer. The world almost ended last month, and we were all activated."
"So you're a hero?"
"Yeah... Wanna hear the weirdest part? The Big Bad's head minion looked just like Captain Hammer!"
Billy chuckled a little evilly. "I always knew he was a tool. And nice job changing the subject."
"Right. You're really okay with me being... well..."
"Vi, there is nothing you will ever do that can make me love you less. Even if you decided to become Johnny Snow's sidekick. But if you do decide on that, I'm going to have to ground you."
"Yeah, I'm not going to be a cape and tights superhero. Just a stronger than average girl who fights vampires."
"Wait, you fight vampires? Since when? I told your watcher to keep you away from them!"
"You're the one who... You know what, of course you are. Mr. Giles wondered why my watcher was raising me in concert with my father; I should have known that you just went all protective and paranoid on her," Vi said, smiling sadly at the man.
"I just don't want you to get..."
"Dad, I know it hurt you when Mom died. I get that. And you don't even have any pictures of her. But I can take care of myself, and if the worst should happen, I'll go having done something to better the world. That counts for something, right?"
"Just stay away from cheesy, overly-muscled, chisel-jawed tools who claim to be a hero and end up getting the love of your life killed."
"I promise, Dad. Besides, Buffy's the only one attracted to Angel."
