Admittedly, Itsuki's pretty sure she'd rather have the conversation for smuggling her transformation trinket onto her own person than for going into potential combat unarmed. Not that she knows Light realized anything, so. Oops. Satisfied it's safe enough in her hoodie, she nods as she rejoins Light. "Probably, although there are some... special cases." Heaven forbid Momoko showed up... or Dark Precure somehow arrived, the train would turn into a battleground in seconds. The grimace on her face probably communicates her meaning well enough. "No, if anyone shows up, I'm going to hope it's Erika-san and panic if it's anyone else."
