The day after (Closed RP for Naomi and Soichiro)
Shortly after the previous day's bout of fortunately-unconsummated potion-induced passion had worn off, Naomi reentered the Gryffindor common room, carrying a few books that discussed love potions. She sat down and began to read about detection methods - the likely-doctored coffee was long washed away, but educating herself on the potential risk sounded like a good idea nevertheless, and maybe there would be a way to detect it in the bloodstream or the like, as with the Muggle counterparts.
