"That seems a pretty big mistake to make." Howe does that even happen? Papyrus is certainly anything but dead, appearances otherwise. He's far too annoying to be deceased. The distant memory of a conversation they've had before tickles at the back of his mind, something he'd almost forgotten. Something about a time loop, though Lambert had been more concerned with teasing Papyrus than getting answers out of him back then.

"Doesn't sound like waiting for him to tell you anything has worked out for you," is what he comments, leveling his sword at Papyrus speculatively. "Maybe you should just beat it out of him again instead."

He's joking. Mostly. While Lambert doesn't have anything against Sans, he also has to say he has no worries about inciting people to violence when the situation calls for it. Speaking of which...

"Show me what you got."
