[Someone is very, very, very suspicious of these lanterns. She remembers what happened next time and she is SUSPICIOUS. Everything else happening today is suspicious enough, as well, and she's willing to bet that there are drugged lanterns to be blamed for it (how else could she suddenly be in a yukata, after all!!!1).
She's currently squinting at a row of them, frowning. Everything is too calm right now to start, which only adds to the suspicion.
