Vanessa is the Angel that Grey is looking for but once he finds her, she knocks her car into him and he suffers from temporary memory loss and cannot remember who it is he's supposed to find. Together, they look for answers but Grey is too intimidating for Vanessa and what's worse is her kind are not supposed to have any relationship with the underworld. She's not supposed to feel desire and lust but she can't help the feelings when Grey's around her all the time and he doesn't hide his own emotions from her.
