Talk:Toaru Kagaku no Railgun S Episode 21/@comment-151.227.37.142-20130908122446

Maybe this has been asked before but, can someone tell me why the sister's eyes are no longer blank and vacant. Like, in the case of 10032, in Index her eyes are sort of slate-grey and emotionless, yet here in Railgun they are brown and far more expressive.

Do you think it's just an artistic choice or does it have some meaning?
