come to think of it, i remember there's flashback on ep 1 when Hildegar collapsed in the middle of snow then a silhouette of man appear and found her. is that why she said that she definitely saw him before but couldn't remember exactly when???
I was wondering that too. The other characters are pretty heterogeneous in terms of skin tone, hair color, etc., so it's hard to figure out how they're clocking him so fast.
