Shamrock is Shanks’s twin
When they were kids, they would have been completely identical. I think Garling exploited this in order to poison Roger, giving him the incurable disease that took his life.
But I don’t think Shanks was necessarily the one who did it. Rather I think Garling swapped Shanks with Shamrock at one point, having Shamrock be the one who poisoned Roger. This is probably when Shanks temporarily returned to mariejois.
I think this is why Gaban is in this arc. So Shamrock can ultimately drop the reveal that he’s the one who killed Gaban’s captain.
