Also, I'm doing this one-sidedly cuz there's no side story or a spinoff of his little brother, but if he reasoned with 'i was scared, i will not let you go anymore' fuck him. REMEMBER THIS BE RESPONSIBLE FUCKERS.
I mean.. Yuki (the little bro) shouted "Shinji run" and stopped the big bro from catching/following him cause it was him (little bro) that was afraid not Shinji (I think it was clearly said but I can be wrong)
Did you even realize that Shinji left his brother when he found them naked? I mean they're high schoolers but be responsible, he just ran away like that. He could have stood beside him and properly greet his brother. Tsk tsk. It's kind of disappointing.
