Agree. There's no question the game needs Aiden, or at least one villain. We may not like him, but that's not the point.
Well, would the Dylan route make sense without Aiden and his tasks? To me it seems like his route, would continue as normal. Only advantage I can see is without the threat, Dylan would never be sent to boarding school, giving Ellie the opportunity to do some nude sunbathing in the backyard. But considering despite her popularity, her events like her dance performance or Jules ballet performance are neglected, her first opportunity was PD12, I'm beginning to lose hope that Ellie nude sunbathing will actually be a thing.
