Basically, post your ideas for different personalities that Shinji could have had and how you think they'd come about.
Nihilist!Shinji: Basically House!Shinji. This is essentially a Shinji that's somewhat smarter than he was before and knows it. But he's been hurt by someone. He has no faith in anything and gets quite a kick out of dropping the other shoe on people he views as "deluded."
Keet!Shinji: Shinji with an extremely fun loving personality. Basically, this Shinji had to take care of his guardian in his old home because of some medical condition. So he's well acquainted with suffering. So he tries to make the best of it and keep his spirits up. Essentially, he's a male Tohru Honda or an older Morel Orel.
Emo!Shinji: Nothing bad happened to him...at all. But in his search for some sort of meaning, he latched onto the typical Emo mindset of pseudo-suffering. Like Nihilist!Shinji, just not as erudite or genuine. Maybe he plays guitar and writes songs about how his guardians don't understand him.
