it's really just the Velstadt helm that he recognizes.
it's the little things, really, that make DS2 worthwhile.
like the fact that the game presents you with the Artorias greatsword, the majestic greatsword, at the bottom of that curse deathtrap tower. which specifies that all it's previous users were left handed.
Then you fight Fume Knight and realize upon the shift to phase 2 of the fight, that Raime is actually left handed, and neither of his 2 weapons are his original gear, and he had a Greatshield he left behind, lost in the salamander pit in the Forest, and a ring that reduces stamina loss when blocking, and you realize he was a left handed sword and board [chameleon sting]er. And that majestic greatsword had to come from somewhere. I mean, it's not on a corpse, but in an iron chest.
