I wonder who rescued Luffy. I saw a lot of people guessing Kizaru previously, but that seems pretty unlikely now. I like the idea of Boa's clone saving him, but no strong evidence for that.
I think that panel where oda shows Borsalino is either he did it or he know something. He seems pretty happy with that punch though, so i still think he did it, no one is that fast to avoid attention.
