Shanks and Luffy in “Unfinished Business”

[to Luffy on getting his arm bitten off] It's just an arm. I've got another one. I'm just glad you're alright.

[later] So you're leaving?

Yeah. It was a nice extended vacation but we have to part ways now. I bet you'll miss me right?

Yeah but this time's different. I won't beg you to take me with you. Cuz I'm gonna be a pirate all on my own.

I wouldn't take you with me anyway. You'll never make it as a pirate.

No! I will make it as a pirate! Someday I'm gonna gather a crew even better than yours and I'm gonna find the greatest treasure in the world, and then I'll be King of the Pirates! I'll show you!

You think you'll surpass us? [gives Luffy his straw hat] In that case I'll leave this hat to you. It means more to me than anything in the world so you better take good care of it, you hear me? I want you to bring this hat back to me someday in good condition, and only once you've become a great pirate.
