It wasn't just Pops you idiot. [He doesn't cry, his mild irritation with Ace's general stupidity helping him through that. At least it's useful for something.]

It was you too. We wanted to save you too.

The only reason we forgive ourselves is because you were protecting Luffy, as we'll try to continue to do in the future. So don't you dare say it wasn't enough or that you didn't save him. You did, and that's the way it is.
