I hope you do remember my post regarding this. The effect of the serum in LE was worn off right after you had sex with the girl who had drunk it, despite they were breathing it all the time they were there. New serum in ToN can back up this fact. Too much time has passed for it still to be in the water, even though if the village store the water in reserve pools. As i was writing this i got to thinking. Maybe, at some point, Janet has bought the serum since she is running errands or stumbled upon Valerie who had given her sample to try.
Yep, she seems so adorable, innocent, caring. Maybe there is more to her than just meets the eye and we get to see her darker side to make things naughtier

. Ohh...too many questions and very few answers.
