“Yeah, parallel timelines, yeah, that would work…” Sirius’ face lit up though the prospect of James and Lily dying in any universe left a bitter aftertaste. “Maybe by taking us here, Petersen created such a parallelism. No, that doesn’t fit. The staff who’s been taken back and returned here didn’t remember anything while in their original world. But their memories returned, when they got here again. Maybe he uses something like a memory charm before he sends us back. Then all I have to do is to make sure that I have something with me that reminds me of it. A tattoo or, yes, or scars. I could write on my arm that I should not trust Peter. Or I could make sure I die here, so I can’t have that bloody rubbish idea.” Sirius smiled. He had plan. Not the best thought-through plan. But that never stopped Sirius, did it? No, it was a plan. And it work.
