So, any thoughts on the characters' types?
I'll suggest xNFJ for Celine and some xNxP for Jesse. It's really hard to tell whether they prefer introversion or extraversion actually. My initial impression was INFJ for Celine (in before sunrise) but in the sequel she seems waay more E. Seems like a very subtle line for her, anyways.
Jesse... I don't know, a very rational ENFP?
