S01E703 — The Raven Mystery Train (Junction)

Conan is still investigating the case. He asks the suspects to be filmed while running. Masumi leaves the group, intending to take the recordings to the Detective Boys to ask them which looks most like the masked suspect they chased earlier. On the way, Amuro notices her from a room and contacts someone with his cellphone. Scar Akai then walks past the mysterious woman who had come with Subaru. The woman says something to Scar Akai as he passes which startles him. But before he can follow her, Masumi confronts him and asks, "Who are you?" Scar Akai smiles and tells Masumi, "you haven't changed a bit." and he reveals his face to her. Masumi, surprised and confused, responds with "Shu-nii". (nii is Japanese suffix to call an older brother). She questions Scar Akai, stating that she heard that Shuichi had died. Masumi and Scar Akai's confrontation ends abruptly when Scar Akai knocks Masumi unconscious with a taser.
