The time has come, Vector, I don't need you anymore!
He's angry and upset and still hopes to survive this. He's Vector, after all, how many times has he already survived, faced death and laughed at it and went on with his life and this shouldn't be any different. So why is he still hoping if he knows it's not over yet, knows it can't be over yet.
And there's the boy, the boy who controls the embodiment of hope itself, the boy who is the embodiment of hope himself and he grabs his hand and holds it and it's ridiculous. He's not Shingetsu, there's no Shingetsu in the first place, there has never been and there never will be Shingetsu, Shingetsu was just an act.
He doesn't care about the human prince who lived on earth centuries ago, because it's just the past, nothing that matters, and he's still Vector – always Vector! – never changing, never wanting to change.
Even if you don't have a heart, I'll trust you, until you finally have one!
It's when he realizes that he is in fact kind of stuck here without any plans to escape and the only thing keeping him here is the boy's hand holding him. So, yeah, Don Thousand won't let him escape but, hey, at least he does have the possibility of taking that stupid brat with him.
He grabs the boy, screams at him, shouts they're gonna go down together, but the boy's still smiling, tears of relief falling from his cheeks as if they've ever been friends, as if he has never betrayed him.
Yeah, let's start it over with me, Shingetsu, 'cause you're our friend from now on!
It's calm now, his body and his mind are clear and focused, and he sees things clearer than ever, knows that dragging this boy won't help him now, knows there isn't any time left for him to enjoy his pain, so where's the point anyway?
He sees that woman with long, light blue hair smiling at him. In his memories, she's always smiling at him, the only person smiling at him – his mother.
How can I abandon my friend?
But then he realizes that there is actually another person smiling at him, and that person's not out of reach like his mother, but in fact right beside him now, smiling at him in the same way his mother used to.
It's only that boy and his mother smiling, and now he's smiling, too, and it feels like the first time in centuries, probably actually is. He lets go of the boy's – of Yuma's hands.
"I'm coming, mother!"
Sayounara, Yuma-kun.
