Shu, please just die already. I mean you're the worst protagonist of this season. You are also just a waste and dumb. Just for the sake of all anime, please just die. Though, surprisingly; is this episode actually the start on granting my wish?
So we see Shu literally suffer the most for the first time. (It may seem like I'm cruel and cold but Shu is definitely the worst protagonist of this season.) He somehow became delusional and confused through a weird reason that doesn't make any sense since he's obliviously "peaceful" for this entire episode. The "problem" that Shu has also makes him scared of everyone which is quite neat. For the first time, I actually like an episode of Guilty Crown which is this. But, there is really nothing I can discuss about besides Shu suffering mentally. Now, will Shu die on the next episode and the female candidates won't waste themselves on him?
Conclusion: Cool weird episode of Shu suffering.
