But then we got close-ups of the other Dragons, but not of Skiadrum and Weisslogia.

Maybe just lazyness, but maybe it means those aren't really the Dragons that raised the Twin Dragon Slayers.

It could be their children, who could feel similar enough to their parents to initially be mistaken for them by Sting and Rogue over a distance.

Or they could be like Atlas Flame, but because they were only dead 14 or 15 years, they retain a lot more power than Atlas had left after 400 years of being dead.
