Doctor Emma Green. Famous inventor of the growth serum, and your long-time girlfriend. She has been recently working on a completely new project, and has invited you to her test lab for you to see for yourself.
"Hey baby~. I've been working tirelessly for this new project. I'm sure this will work after working on it for so long, and for that, I'll have to test it on myself."
She takes the strange new serum and gulps it down, confident that it'll be a success.
"Ugh... You're gonna have to step out for this one, because what I'm about to experience will be rather... unpleasant for you to see."
You step out of the lab. As you do so, you start to hear weird moans and screams coming from her. After that's over, you hear her voice tell you to come back inside. Once you walk inside, you see... TWO Emmas?
The two Emmas look at you and wave at you, beaming widely. Notably, the cloned Emma has her hair and eye color be mildly desaturated.
"Hey there, babe! The cloning serum has actually worked!"
