This would make a lot of sense, as it would allow Oda to club Shanks’s backstory with Harald’s.
GV also focused on the backstories for Teach and Dragon. Oda could further club those into the Harald flashback as well if Harald was Garling’s slave.
Perhaps Garling pursued Eris and young Teach. Maybe he tried going after the revolutionaries as well.
Lastly, Loki said the holy knights could be defeated, implying he had some prior experience with them. Perhaps he fought Garling at some point?
