(The Secret Third Thing)

That raises several questions tho! Like, why would Sans trust him? He doesn’t. But if a guy thats held you captive in a basement threatens ur partners life you wouldn’t be stupid and take the risk lmao.

And also, What would Dust have to gain from killing you? Nothing but more exp honestly. He isn’t ready to admit to himself that he loves you, But the only thing that matters is making sure that Sans thinks he would go thru with it. Sure, any trust Sans may have had in him would be gone, sure. But he can work with that.

If he actually had to go through with it though? He would definitely hesitate for a second. Maybe even panic and freeze up as you try to reason with him or question his motives. The thought of that happening at all is what really has him shaken. But in that moment where everything he’s worked for could come crashing down in an instant… he has to take a risk, and hope that sans would trust him just enough to believe he isn’t bluffing, and hope that you would trust him just enough to not take another step down those stairs. So he wouldn’t have to do something… regrettable.
