Honestly the fact that he's talking to a minor again creeps me out more than the pad. Primarily because the pad literally just looks like he poured Kool-Aid or something on it, so I doubt whatever's on there actually came out of him. Unless he has some serious kidney issues, that is.
Not to get gross, but there would be more uh... "chunks" if this was the real deal. Periods aren't just blood- they're the lining of the uterus, i.e., tissue. You know the consistency egg drop soup has, with a thick broth and wispy little egg noodles? Well, that's pretty much the consistency the blood and tissue have. Sorry if anyone was eating Chinese food while reading this.
