I know for sure she has a little packet with her. I remember talking to 'em on Tumblr once and they said they had an idea of her trying to get a tissue out and then all of them kinda flying out.Or did that actually happen? I can't remember.
Also there are heavy implies... I just made up that term... HEAVY IMPLIES that Vinyl has allergies too. I always voice her character with a stuffed up nose.
