Ok, another quick question; can our characters remember things from the human world that aren't directly connected with their lives, like pop culture references. My idea is that Cal makes frequent pop culture references only to question and get angered over the fact that he can remember something stupid like that, but not who he is

I'm leaning towards no. Direct pop culture references aren't very tasteful, in my opinion, but if you want to make subtle references, go for it. In Explores of Sky, IIRC, one of the characters mentions hidden villages full of ninjas, a reference to Naruto. If you want to go that route and indirectly reference things without using names, I wouldn't have a problem, but I don't think I want direct references.
