[Sans is very capable of worrying and he's doing that right now. Papyrus's distraction doesn't pull his thoughts entirely away from the emotion issue, but he does at least look away from his phone, as much as he ever looks away from anything.]

I can't do anything about the emotions right now. [Not unless he wants to drown Papyrus in negative feelings, which he doesn't.] Grabbing car batteries out of some cars, sure, I can manage that. [It's not much, but at least he's not entirely useless.]
