Some of these images we've seen before, most we have not. What is particularly interesting is the inclusion of "Young" versions of the Lords, suggesting either flashback sequences or some kind of de-aging magic.
UPDATE: Or just younger characters. They're the sons, not the same people. I'm going to blame this memory lapse on the kind of painkillers that make you sleep for four hours.
I was thinking it could go either way – those who have been paying close attention will know that the film already contains some kind of transforming spells, but also that it details an old curse, passed down through the years – until I looked at Dingwall's blue marks, which would appear to have progressed throughout his life, and so I think the flashback option is just a little more likely.
