She's more narcissistic as you remember

“That‘s... not....”

“Possible?,” she ends your sentence. “Well I‘m the living proof that everything is; me becoming God included. Watch this.” Ava holds her hand up and briefly wiggles her fingers, which causes a bright something that looked like a opaque disc to flash into existence over her palm. Tiny white spots blink all over and around it. You notice that the plate spins around its own axis, then realize how familiar it actually looked. It isn‘t a disc. Rather a spiral. A spiral galaxy hovers like a hologram above Ava‘s hand, sparkling with billion suns and a blinding center in the middle.

“Scale, honey,” she says and sounds as if that‘d explain everything. “It all comes down to scale and magnitude. How insignificant humanity, or even this dimension is. Nobody here could guess. Or can you grasp that I just created billions of civilisations, each with its own feigned history, and only one is portraying humanity?” The galaxy shrinks and becomes just a tiny spark, then another appeares, then ten others, then countless others, as if fireflies are swirling around Ava‘s fingers and not entire galaxies. The girl grinned and beholds her creation. “I‘ve got to admit that it took me some months to get used to my new... rank. That I‘m standing above everything, even logic. And all that mandatory responsibility bullshit that I thought would come with it. Until I asked myself why God should bow down to duties anyway. Who should question me? Challenge me? God should be allowed to do anything what comes to your mind, or dare I say, to my mind. The winner takes it all. So it‘s simply more fun for me to do whatever the fuck I want.”

Ava balls her fist and literally crushed the tiny cosmos between her fingers, ending it forever as spontaneously as it had been created. Dust particles trickle onto the table beneath and ripple to the floor as your all-powerful girlfriend reaches for a chocolate croissant and bites off a piece. She sighs with relish.
