Seeing Senya go all out finally against Jinka was really nice. At this point, Senya isn't stronger than Jinka, but that wasn't the goal. The goal is to bring Senya back.
I think this episode once again highlights Shinsuke's growth and maturity. Seeing the wall that separates Jinka's heart really empathizes that Jinka heart, shows that he has cut himself off from what he was. Though, he just needed to remember what he had. Shinsuke offering the 4 of them to eat together could bring that. Then it was up to Tama because she was Jinka's inspiration and what he did everything for. Having Tama back was reassurance to Jinka that he wasn't alone because he got tricked that he killed Tama. Because of the Void People's involvement, they couldn't save Jinka before they escaped.
Though, things aren't so simple. It is cool to see the protagonists of both Part 1 and Part 2 interact. For Jinka each tail represents something and the last tail being emptiness, is interesting because of the emptiness that Jinka felt. I wonder if he needed to see the other two alongside Tama, but I loved how despite meeting for the first time, these two became instant friends. It's thanks to Senya that Jinka got to see Tama again, and it is thanks to Jinka that Senya got to meet Shinsuke who changed his life for the better.
Very excited about how the epilogue will wrap this up.
