I would’ve preferred Shanks to have been the name Roger gave him rather than the one he was born with.
In fact, Shanks should have a birth name, the only one Garling acknowledges.
Shamrock is a dumb name for a CD.
Shanks having two names could’ve added another layer to the mystery of who met with the elders.
Imagine we got to see a young Shanks in Knight attire being referred to by another name before we find out it isn’t his brother’s name.
