Well, strange as it may sound, where I come from, I've met him before.

[She doesn't elaborate, but mage.. templar.. maybe Sansa can figure it out.]

But when I arrived here, he said he never met me. He said he met my brother, Carver. Where I come from, my brother was killed when my family escaped our home and moved to Kirkwall.

I've thought much about this. I suspect the reason Carver may have lived where Ser Cullen is from is because I was the one who died instead, protecting our mother as Carver did where I come from.

I have not asked Ser Cullen what I think to be true, though I'm not sure it really matters either way.
