[Vash is pleasantly surprise that Knives listened to his request and didn't touch him. Something had happened and it wasn't just the hair color.] I picked my own door just like you did. [He wants to plant that idea in Knives's mind. That a human didn't mark him. In a way his own choice is what did it.] It showed up when I picked the door. [No one forced him or actually held him down to tattoo him.

He smiles a warm and happy smile; although it won't take Knives any effort to see it's a mostly empty one.] I don't think any of the submissives here are inferior. Just a luck of a draw. That's all. Nothing to get upset about.

And I'm not more than anyone else here. Mark or no mark. [He ends with that. It's the point Vash wants to address the most and believes to be the most important. Also hoping to redirect Knives's anger from the world to him.]
