Monogatari Series: Second Season EP19 - Shinobu Time, Part Three

After Shinobu tells Koyomi her story, they realize that Yotsugi was overhearing their entire conversation and after Mayoi awakens, they start discussing ways to deal with the darkness being before it appears before them. Koyomi, Mayoi and Yotsugi manage to escape again, but Koyomi is knocked out cold by the shock of Yotsugi's jumping just to awaken several hours later and learn that they unwillingly left Shinobu behind. As Koyomi's vampire powers had not disappeared yet, they conclude that Shinobu is still alive but with Koyomi's powers weakening, it means that they have to find her before she is killed for good. Having no clue about what to do, they decide to contact Izuko Gaen who might provide some advice and when they decide to take shelter in a house, Izuko herself opens the door for them, much to their surprise.
