Review Detail of Tim_ in Pokemon - A Mystical Journey

This was pretty solid until volume 4. At that point the author completely forgets everything about the MC and decides he needs to experience a traumatic event and have issues and personality changes in the aftermath. Which is fine, but the traumatic event itself is less impactful than four different situations earlier in the story. The entire thing feels super fake/forced. Writing around that area has huge issues with telling us stuff vs showing it. I swear I read lines like the following at least 10+ times. "He won't be the same after this", "This could change him forever", etc. The huge kicker is he starts acting all emotional when back at home. He showed zero personality changes earlier in the story (after kidnappings, murdering poachers, selling pokemon on black market, murdering pokemon to use as food for his current team). So why is he acting like a baby now?
