The alicorn just perks up
"M-My story?...."
Then after a bit she just sighs and returns to having her eyes closed while catloafing
"I....Don't exactly remember much, I just remember a....Bright flash of light or something like that, then... I think I didn't exactly feel like being myself in the Unity.... But I remember doing... Things I can't feel proud of, instead they could leave a mark of guilt, yet the others seemed completely ok with it... But I wasn't as much as them.
I think that made them doubt, but before something happened, we were somewhere around... Canterlot was it?... I was myself again... And I could remember some things, from before the flash, I think; the others started looking for me... But I remembered enough to want to walk away and escape. Started wandering around for....I kind of lost track, but I think it was 2 days."
