The Lore Savant
I cant defend either caster or beserker, but perhaps beserker didnt mean you as Death, but death as in like the supreme force, saying he is above that force? Hell if I know.
Capital 'D' was used and he was talking directly to Saber, who is supposed to be the only person to actually know that Caster is Death, suggesting it's some kind of shared knowledge between them.
