I'm pretty sure Shinn had a copy of the Oreimo 1 & 2 dvds hidden in his room somewhere. He'd watch a few episodes then cry himself to sleep while listening to his sister's message box.
Well... that would definitely explain a lot.
What did Shinn Asuka do that wasn't sociopathic again?
I mean "Hey Athrun IJIZZ JIZZ JIZZ".failed to kill your bro
"Hey Luna, IJIZZ JIZZ JIZZ."failed to kill your sister
"Hey Cagalli your dad is the one to blame for all the people who died. Nevermind that more people would be dead if he hadn't done what he did. That's right, accept my logic as flawless. JIZZ JIZZ JIZZ."
"You're right, Rei, I should definitely believe that our boss isn't unhinged. JIZZ JIZZ JIZZ."
"So my girlfriend totally justbut I'm gonna hate the guy whowent on a rampage leveling Eastern Europe"put her out of her misery instead of her.
"Hey this boat is full of people who have loved ones whose lives will be ruined if I kill them! Just like how my life was ruined by war! RIP RIP RIP RIP."
Shinn Asuka is a sociopath. He's like if Kamille Bidan didn't grow the fuck up.
I know you don't like Shinn that much, but Cagalli's dad did kinda drop the ball in the Earth Alliance invasion in the original series. And the Luna thing is just... surreal more than anything else. Like, there is no way any rational human being, let alone one in the military, would ever be that... chill about what just happened.
His exchanges with Rey is fucking hilarious though. Like, his "DON'T LISTEN TO [X] SHINN!" shtick is so frequent, so obvious, and so forced that I'm surprised that no character observing this didn't ask him "Hey Rey... you're acting kinda suspicious right now. What's that about Rau La Cruset?"
I am still completely convinced that there was some grand and consistent character development between Shinn and Stella that the directors just neglected to share with the rest of the class at any point other than that "
Like, Shinn has some really, really big character flaws, but so much of this just plays off of the epically bad writing in this show.
