Note: (Except for Flaming Familiar and Conjure Flame Atronach) Serana cannot learn fire spells. She's a vampire, and even if cured she would still have a fear of fire. Flaming Familiar is the exception because it technically is a magic homing missile, summoned from a distance. Same with the Flame Atronach.
