Nitta explains that he had left his phone behind somewhere, which he needs as he is expecting an important call. Nitta opts to go alone to search for it, but Mutta, being the leader, decides it would be best to search alongside him at night once they set up camp. Along the way, Nitta explains he is waiting for a call from his younger brother, Kazuya, who he hasn't spoken to in two years. Mutta suspects that Nitta may have dropped his phone near the previous food crate when Mutta tackled him, which motivates Nitta to rush to its location. Arriving at the crate, Nitta finds his phone as it flashes, only to find he had barely missed a call from Kazuya. (thetvdb.com)
