I wonder what Kian was talking about... at first, I thought maybe he remembers their past lives as well, but that wasn't the vibe at all before. Like, if he did, I feel like he'd recognize Silla's knowledge of what he wants for the future and the certainty of her magical power and stone as signs she does remember, instead of saying it would be a miracle. This makes me think we're meant to THINK he remembers the past but actually something happened in Priscilla's childhood with Kian. Something that will probably tie into their past and present lives together :)
