It's Because I... Ran Into You

As Chihiro tries to explain things to Ranko, Rea follows Bābu to a field of hydrangea leaves and eats some, which helps her regain her senses and cure her rigor mortis. Jogorō explains to Chihiro that Rea needs to continue eating hydrangea leaves to avoid becoming a corpse, though mentions it is not a permanent solution. As Chihiro manages to convince his father to let Rea stay at their home, he begins recording his observations of her. As Chihiro and Rea take a walk that night, Rea ends up injuring Chihiro slightly whilst saving him from a car and begins curiously licking his wounds.
