Everything changed In Noora Montgomery life the moment Damon Salvatore tried to bite her.It wasn't a success on his end , her hand had managed to touch his left arm when a light appeared in the palm of her hand burning and scaring the dark haired vampire before he even had a chance to sink his teeth into her porcelain skin.
Still till this day
Damon Salvatore has a hand print of her hand on his left upper arm . It was then she knew the truth not only of what she was but
that all the monsters that went bump in the night were real .Vampires werewolves ,witches oh and lets not forget Guardians
protectors of the universe blah blah blah .
Which was her species apparently , well according to Stefan Salvatore . She didn't quiet believe it at first Laughing as he explained to her she was Angel well half angel half human . it wasn't until Leo Fray arrived who was just like her showed her not only what she could do but her purpose in this fucked up world.
