“Lyra…“ You step away from Aunt Bon-Bon, who walks towards Lyra. The other Lyra.
“Bon-Bon, is everything alright?“ Her expression looks clouded with worry.
“Yes,“ Bon-Bon replies, then shakes her head, “No… Lyra, I have to go.“
They both reach for each others’ hands and hold on.
“You’ll be back though, right?“
“Yes… But I won’t remember any of this.“ Lyra’s mouth hangs open. “I won’t remember anything that happened before I left for Paris.“
“I-I don’t understand.“ Lyra’s breathing is heavy and you can tell she’s already on the verge of crying.
Bon-Bon looks away, “I don’t understand either, but when I come back- the last time I’ll have seen you will be before I left. It’ll be like the last three days never happened. It’ll be like I never got back early.“
Lyra’s lower lip quivers and tears start to drip from her eyes, “Is this a dream?”
“I don’t know.” Bon-Bon inhales deeply and you see her start to cry too, ”But I love you,“ you watch Bon-Bon squeeze Lyra’s hand, “And I’ll still love you when I get back. I promise.“

All at once it hits you and you cover your mouth to silence your gasp. This world’s Bon-Bon is in some place called Paris. And Bon-Bon, your Bon-Bon, was pretending to be this Lyra’s girlfriend. You stare at the pain and confusion in this Lyra’s face and… It’s not right. Bon-Bon would never hurt anypony.
