he was in the endgame 12 panel...
yeah oda just silhouetted her for no reason even tho he revealed BB's mom in the same chapter...
Not to mention Garling actually marrying her. From what we know of garling, he is not someone who marries a random nobody.
She was from an island of Davys and Ds. She is the one who gave shank his iconic unique red hair. The only hair that oda uses special tone for.
That chapter is not the one where they declared war with elfab. The declaration of war came after sham went back.
That chapter is important because of shamrock being revealed.
He was likely in the large splash you're referring to, and
top 12 well... how many antagonists do you think are left?
The mother was not featured by silhouette in chapter 1137. You're conflating things. "Introducing Shamrock" is the chapter where we get info dumps about the history of the Giants, and if you want to say Shamrock himself is relevant then all you can point to besides his physical appearance is what he says: the seas belonged to them. Now we know specifically that "
Elbaf is the D" and this ties into many earlier hints. As time goes on it will tie into many of the greatest mysteries. Shanks having an evil twin is not, itself, relevant to Roger and the history of the world.
