Morning back to you, brother. [He says it with a brief wave of the hand with the spatula, but without his usual energy or exuberant cheer. Just a greeting, with a half-smile. Now that they've talked, and it's clear that he's... not feeling it, not really, and they're planning to do something like this? No sense faking it that hard. He gets back to checking the pancakes, then glances Sans's way again.]

The... batter, in that bowl. It's just the box mix, nothing else added. I'm sprinkling these in, in the pan itself. [The batteries, which he gestures to the pile by the stovetop. If Sans wants to make himself pancakes - in a different pan, and maybe after he has a chance to check Papyrus for honesty. If it works like that.]
