"Because Ace," Marco's voice dropped to a rare, extremely serious tone. "It's been my job to look over you little idiots for so long, it's the only thing that matters to me with Pops gone. I'm not asking you to remember something you can't or be something you're not. And since you don't remember me, I'll let it slide this once. But know this. A Whitebeard pirate never turns his back on a crewmember. I don't care what you wear, or who you say you are. As long as you've still got it in here," Marco tapped Ace's chest over his heart, "And I've still got it in here," he pointed to his head referring to the memories, "You will always be a nakama. And nothing, I mean nothing will ever change that. Not all the spells or time-space crap in the universe. Got it?"
