I think this was the future the seer saw when Michael was explained about her when he went to SkyHall. I don't think this has to necessarily have to be the future where Layla dies. Or something...
wutdafuq??? Author , do NOT make this a crossover.
& Leilah died seriously ? what happened to her child ??? & why the advance chapter like this one if you might change the story later down the line? E.G. Leilah & her child being alive...
