"15.) Is your character an early morning bird or a night owl? "
Both Fiole and Frank are early risers. They love a long day and like to get started early. Both do love sunsets, but after sundown neither of them like working. Sunset to predawn is time for relaxing. They feel that you should wake up early enough that you are ready for a full day of work or play as soon as the sun is fully risen.
Supers don't need as much sleep as normal people and 4 hours is a full night sleep for them. Fiole still likes to spend any other dark hours as down time, time to "sharpen her saw."
Frank makes due with less sleep because he feels like it is time he could be doing something else, and he doesn't like to think there is anything he can't do (he tries to keep up with Fiole). He knows how important sleep is and sleeps a full night when there is no pressing need for him to be awake.
Neither of them have any trouble getting to sleep or staying asleep.
