[Sora looks like he's actually considering the answer to this for a moment, mostly because he wasn't expecting the question (don't most people care if other people are sick?), then shrugs.]

I don't know, wouldn't it be better to warn everyone to stop drinking it if it's bad? Some people might be drinking more than you. Couldn't that make them even worse?

[Though he looks uncertain. He's definitely no doctor. He's kind of taking this "bad drink" business sort of like a case of food poisoning.]
