Spoiler
W truly stands out in that you can see the polish that went into it. Like if this were a lesser Kamen Rider series, Akiko would probably be some superficial girl whose face-removal wouldn't warrant an emotional response But since she's important to Philip, Shoutarou, and to the audience, lifting her head up and seeing her face gone is genuinely shocking
So many great things about this episode. Shoutarou finally putting the hat on, no longer needing a father figure or a partner to do it for him. Shoutarou is half-boiled no longer. And it's an effective moment, since we see all the soul searching he goes through and what it takes to push him to that place
Poor Saeko, no one to grieve for her. It's funny how Philip acts like Wakana is his only sister. It's never really "let's save Wakana and Saeko!". Although given their past and the nature of their relationship, maybe this is a natural thing for him to feel?
No episode title? Is it because the letters only existed as part of the Philip lookup theme, and now that he's gone, it doesn't count?
Was that flashback supposed to explain Wakana's change of heart? Because if it was, it's sort of lame and doesn't explain her drastic personality change
