User blog comment:Mattalamode/A Season 5 Retrospective Review: The Problem Child/@comment-24972567-20171117190249

I thought 'The Ex' gave something new to the Rob story arc, after 'The Rerun' when it's hard to still be enemies, Gumball misses the days they were for the adventure, there was something different in each season for Robs story arc: season 1: he's a non speaking extra, season 2: he expects to be remembered despite being a non speaking extra before, season 3: he's been put in the void but escapes and vows to become his nemesis, season 4: when he begins trying to destroy Gumball and Darwin and season 5, as I say above, so season 6 may end that off properly.

It's been great commenting with you too Matt, and when you say most controversial critic, don't forget about me with my opinions in the vast minority they are ;)
