Realized I missed responding to a couple of things 
@Nocturnal_Stillness Did you get to play though the Face path where you bring up your past with JJ in the Chapter 10 promo? I tried to provide that sort of catharsis in that route.
@VampLena I can see where you’re coming from, but for me, allowing the player to have both the “dream match” with JJ, as well as a championship match, would be undermining what I felt was the hardest choice in the game. Glory or closure? The best, or your best friend? Your original dream, or your new obsession? It was intentional decision to ensure the player can’t have his/her cake and eat it too.
That being said, if you fight JJ, the champion is Prototype… and can there be any real doubt that, if you can beat JJ, you can beat him?
I didn’t see the need to write it in, but I’m fairly sure you get the championship eventually, anyway – but when you choose to fight JJ, you choose, in my mind, to make your story about JJ, and not about the title, so that’s why the story ends when the fight with JJ ends (or a bit after).
@Galador Oh no! My biggest naming fear
I don’t see any feasible way around it, sadly. Good thing you didn’t name your wrestler Paul Protoype. or worse, JJ Havoc 
@soranre: how to beat Solitary, @RVallant has the right of it - go for the good leg, because the bad one is totally numb and won’t feel pain. The trick to lasting long enough for Solitary’s leg to give way is to always be aggressive, no matter how much damage you seem to be taking. You don’t need to have listened to Super Horns to beat Solitary, but you do need to have done so to have all possible victory options available to you.
@Ninjasplaycardgames2 Oh, just don’t forget there’s a bug in the route of a homosexual male Kayfabe Face, so don’t go that route if you want the JJ romance.
