He'd told Robin it wasn't necessary to wake Luffy up, and really it wasn't, even though it was weird to see him so still laying there. But he was breathing. Sabo knew he was breathing. That was the whole point of hanging up on Koala and sneaking off- to check. It would have probably destroyed him if he'd just gotten the little brother he finally remembered two years ago back only to lose him after being reunited. He'd never be able to face Dragon if he'd stood by while his son died. Hell, he'd never be able to face Ace in the afterlife, either. In fact, he was pretty sure Ace would come back from the dead and beat the shit out of him. (No you dont)
But Luffy (I see you there) was snoring away, dead to the world as Sabo watched. The questions were expected, even if they were… painful. Exspecially with the look Zoro was giving him. His little brother…. really had managed to get a good crew after all. It was good to see it for himself that Luffy had people he could rely on now. So he told them the truth, knowing they'd find his story lacking. After all, amnesia? What kind of lame-ass excuse was that? He'd abandoned his brothers! Left Luffy to try and rescue Ace all on his own! And even after- even then- he was too much of a coward to face his young brother right away….
"Bwawawawa! That is the saddest story ever, Bro!" The cyborg bawled, tears streaming down his face. It was strange to see his cybernetic eye crying, and a little distracting. "Lubyibsolubytoabyou!"
"Huh?"
"'Luffy is so lucky to have you'" Robin translated, not looking up from her book, a smug smile on her face.
"Second Division Comander of the Whitebeards, and Second in command of the Revolutionary Army. You two aimed big, huh?" Zoro grinned, and approving glint in his eye, "Luffy aimed bigger."
Sabo got the feeling the man was suggesting somehow his own drive had still been influenced by his brothers, even with the amnesia. He smiled, even if it was a little shaky, and stood. "Speaking of, I should go. I know he's a bit of a handful, but can you take care of him for me?"
He glanced down at his little brother, the little idiot who didn't know the meaning of restraint in anything he did and watched as Luffy rolled over onto his side, facing the wall. Sabo's mouth went slack slightly as, not for the first time that day, the image overlapped with the past. However unlike before, it didn't overlap with his early childhood - images of Luffy being carried by Ace - but of his time with the Revolutionaries. He blinked, barely noticing as Robin's calm smile turned into more of a grin as Luffy's epitaph really clicked for him. "Strawhat Luffy…. causes a lot of excitement wherever he goes, huh?" Like overthrowing whole countries… how many had it been?
Zoro snorted, "You have no idea. If you think he was bad as a kid, you should try sailing with him."
"That doesn't comfort me." Sabo muttered, hand on the doorknob as he seriously debated telling Koala there was a change of plans and the three of them were going to be sailing with his brother till the idiot learned not to take on every Shichibukai he saw.
