Harald: So you're going to make me your enemy are you?
Gaban: Woah!
Gaban: Way to state the obvious! Like I'm gonna let a madman run around freely
Shanks: Gaban-san, how is it that you know about the weakness of the Holy Knights!?
Gaban: It's because they tried to come steal you from us several times before
Shanks: !?
Holy Knight: There should be a red-haired baby on your ship
Holy Knight: He's undoubtedly our Captain's son so hand him over!

Shanks: Quite the mess...this life of mine

Gaban: ...
Gaban: That my boy is what we call "fate"
Shanks: Gaban-san, I want to save Harald!
Gaban: However, the one who made me aware of the "terrible fate" of becoming a Holy Knight was you
(*this bit is not very legible and was covered by a watermark so I'm guessing based of the bits i can see, though it should be correct, but tbh even though I get what Gaban is saying here it's not computing in my head in relation to Shanks question)
Gaban: Seems like our only hope of saving him is Loki.
