The giant is a very melancholic, dignified old servant who’s feeling betrayed and disappointed in the player (long story, happens before the game, you don’t remember it and you’re only just piecing together what happened). When he dies, he starts slowly sinking in lava with a very sad expression, with a speech about how “You were an example to us all”, lamenting about what happened, etc… And just before being completely immerged, with just his hand still reaching out of lava… “You…” “…are an ass!” And he flips you off. Perfect delivery.
