A few months later...
"Hello. My name is Twilight Sparkle, and I am a sex addict.
"I had to go a long way to find them, but earlier this week, I apologized to two more people who I had wronged. I think I really cleared up some misunderstandings. I hope it'll help. I can't make everything all better, but I tried to do what I could."
With one hand, Indie Twilight tossed her sobriety chip up and caught it.

Indie Twilight carried some wildflowers in her hand, as she walked along the path. She stopped at an upright stone tablet.
"Shiny," Twilight said, "A lot of things have happened these last few months. I escaped from Crystal Prep. Your old friend Cadance helped me transfer into Canterlot High. I don't know what she said to Abacus Cinch, or what she did. But she stopped Cinch from changing my school records to say I was a bad person."
Twilight bent down to lay the flowers on top of the stone. "Even though my physics research is still going well, I haven't tried to publish. I haven't used it to try to win worldwide scientific fame. I used it to help me find something better. Friends who, each in their own way, are nearly as wonderful as you. Can you believe it?"
Twilight knelt, putting her arms around the gravestone. "I know if you were here, you would be so happy. And by the way...you know what this is."
She set an unmarked poker chip on the gravestone. "I just got my three month chip. I thought you might like to have my old one."
Tears dripped onto the stone. "Wherever you are," Twilight said, "I hope you have friends as good as I am so blessed to have. Because I know you deserve them, BBBFF."
She stood up, and walked into the rest of her life.
