Dont feel like promoting but time is incredibly important to Evangeline. She is to the millisecond, her mind thinks about time on the dot. If she is unable to see and count the time, then she starts to mentally crumble.
She also has issues if routines are broken. For Evangeline if things are not exactly as they are planned, then she gets fustrated. She feels as though things are falling apart.
It hints to much larger issues but they are not defined within the world/place it has taken place in.
