Memories… Episode 19

For the first time since Wakaba's death, Ko goes with the Tsukishimas to visit to the sisters' maternal grandparents in the mountains, where they are caught in a snowstorm. While trapped in the house, he and Aoba remember his past visits and playing with Wakaba. Looking through a photo album, Ko recognizes Aoba's uncle, a famous mountain climber, but not his son, Mizuki, who is the same age as Aoba. In the morning, Ko goes into the snowy forest to visit the tree on which he and Wakaba carved their names, which Aoba had then scratched out. He gets lost and Aoba directs him to the tree, where he discovers that Aoba had later carved replacement names. Back home, at the start of spring, Ko and Nakanishi see a strange boy climb up a drain spout to retrieve a woman's hat blown there by the wind. When Ko later visits the batting center, he learns the boy is Mizuki, who is moving in with the Tsukishimas.
