"Hey there!" says Vivienne as you walk inside, stopping dead in the doorway.
"...Vivienne, what the hell!" you exclaim.
Vivienne blushes. "Haha, sorry! It's just that in all the time I've been doing this I realized I've never actually tried being male before, and I had the potion done early, so..."
"That doesn't--that's not--!"
"Tim, please, breathe," says Hope.
You take a deep breath, but as you're about to calmly explain your position, you see Vivienne's body walk in from another room, waving jovially at you. Your arms tremble. "But why, though?!"

Hope gives Vivienne a look of distaste, but then looks down at you. "...Okay, fine."
"Seriously? What about me?" you ask.
"Well it's this, Vivienne's body, or none at all, and you already said you don't want hers."
"Alright, alright. Fine. I'll share."
"Good boy," says Hope with a note of forced cheer. She walks over to your body, Vivienne tilting her head to one side to make room, and affixes you to it.
