Why is it in fanfiction when 'outsiders' from other worlds/times/etc. wind up in modern day Earth so much interesting character development is glossed over in favor of pop culture or music references? There was a short scene at the beginning of Obsessed Nuker's <a href='http://www.fanfiction.net/s/5691064/1/Green_Struggle' target='_blank' rel='nofollow'>Green Struggle</a> where Nanoha has to explain to Fate why she's so familiar with what a nuclear wasteland should look like, but are there any similar scenes in other fics? Has anyone else written such a scene themselves?
