Narratively speaking?
Luffy’s closest pirate ally
The only D member who cares about his name(as far we know)

Don’t you find it that odd? Oda went out of his way to point out all important D members and according to you threw Law in there for the lols?
And this isn’t even all D members alive considering we know Saul was watching this
