The significance of the three of them being Albasian is less important, but that certainly means something to a select few in the grand scheme of things.

I was more interested in the implication of who caused the sun to flicker. The timing of Lag's comment might have meant that he was the cause (and Aria might have taken it that way), but that doesn't mean that it wasn't Sylvette either, since she was born during the same moments as well.
