I was watching the scene where Wille points the gun at August and it's such a brilliant scene for many reasons but the one that hit me the most is that Simon got to see the degree to which Wille was affected by the video.
In the Music Room fight that went down between them in the last episode, Simon basically says that Wille had it easy in terms of facing the repercussions of the video as compared to Simon. And Wille is rightfully offended because Simon fails to understand that just because the manner in which they both suffered was different, it doesn't mean that the suffering itself was any less for Wilhelm.
Like, when Wilhelm points the gun at August, the anger that flashes on his face is not some sort of a "quarrel" between the Royals, it's Wilhelm's pain resurfacing in the form of sheer anger, all the sleepless nights and tears bubbling and making their way into his voice. It's so evident in that scene, how Wilhelm was deeply affected by everything that went down and now that Simon had a chance to bring some justice to both of them, August snooped in and took that chance away from them. Like, Simon must have finally understood that the game is not rigged just for him, but Wilhelm is as much of a victim as Simon is. That Wilhelm's hurt ran so deep that he was ready to blow off his own cousin's head. And it could be one of the realizations that helped Simon understand that it's not him vs Wille, they both were equally devastated by August's actions and even more so, Wille's loyalty will always lie with what's right, and with Simon.
