What are your current thoughts on Gaster’s motives with the Secret Bosses, if you had to give your best guess?
To be completely honest, I'm of the mind that he doesn't necessarily have malicious intent with breaking their senses of reality (if he is the one doing it), but he severely misjudges how they're going to take the information he gives them.
So he's less of a villainous force, and more of a cryptid that flits in the corner of your eye, and as soon as you turn your head like "What? What was that?" your croissant has gone missing.
