Ep 19. Separated x Diary x Soaked

Gon, Killua, and Leorio continue their journey towards Yorknew City, with Kurapika still absent. The trio passes through a town where they meet a little girl named Retz, who is hiding a secret. Retz is searching for her brother who has gone missing, and asks the team to help her find him. They follow her to a nearby hot spring where she reveals that her brother left behind his diary filled with clues on where he might have gone. The diary also contains a strange ritual that can supposedly grant anyone's wish.

Gon, Killua, and Leorio help Retz decipher the diary and follow the clues to a cave where they believe her brother may be. As they proceed through the cave, they encounter different challenges including a water monster that attacks them in a narrow passage. The trio manages to defeat the monster and continue on their way.

Along the way, the group is separated during an earthquake, and each of them is forced to navigate through different paths in the pitch black darkness. Gon uses his heightened senses to make his way safely, while Killua relies on his training to get out of a sticky situation. Leorio, on the other hand, is left alone and scared in complete darkness.

Despite their separation, the team eventually reunites and continue their search for Retz's brother. They eventually find him in a hidden room inside the cave, but discover that he has been dead for quite some time. They also find evidence that Retz's brother had been attempting the ritual from the diary to bring their deceased father back to life. The team realizes that the ritual is nothing but a hoax, and Retz's brother was most likely killed while attempting it.

Retz is devastated by the news and refuses to believe that her brother is truly dead. Gon, Killua, and Leorio comfort her as best they can and promise to stay with her until she is ready to continue her journey. All the while, they keep a watchful eye out for any other dangers in the cave.

As they make their way back to the surface, the team reflects on their own families and how easily they take them for granted. They vow to do their best to stay together as they continue their own journey. The team emerges from the cave, and Retz thanks them for their help. Gon, Killua, and Leorio continue their journey, now more determined than ever to become stronger and face whatever challenges come their way.

In conclusion, Separated x Diary x Soaked is a poignant and introspective episode that highlights the importance of family and friendship in the face of adversity. The group faces many challenges and obstacles throughout the episode, but ultimately comes out stronger for it. The emotional weight of Retz's story helps to ground the fantastical elements of the show and reminds us of the very real stakes at play in the world of Hunter x Hunter.
