Between not aging a single bit from that flashback till now and how sad he was last chapter when he said he'd be back, Harten seems like he's got a curse of immortality (or something like that).
It might be obvious that the blacksmith’s lip and eye scar are from his injuries in the flashback, but you can also see that Kiri, his daughter, also has a star-shaped scar on her forehead, and in the flashback her forehead is bleeding!
Very cool attention to detail.
