Shojo does. That's all that matters.
You responded to him, but I don't think you countered his points at all.
Also:
What you find "highly unlikely", as a reader of the comic with omniscient information, is a lot less relevant than "What Shojo thinks he needs to do."
"Why not try anything you aren't sure won't work"? That's your defense? Really? I dunno, here's one reason: Shojo believes he's only got one shot at this and has to make sure he gets it right the first time.
How would Nale create a believable illusion of a person he's never met or seen?
