She calls her wicked wren.
It's kind of unfair, she isn't really wicked and hates when anyone calls her anything but Nessie the name her dear jacob had given her.
But she thought wicked was appropriate after all she was her wicked stepmother.
She had been born a few months before Renesmee reached full maturity.
Jacob hadn't even been there, Renesmee had had something so important to do with him that he couldn't even watch his daughter be born. Her mother Leah had never forgiven him. She hadn't either.
Until she turned three and The Loch Ness monster discovered she couldn't have children the Cullen's couldn't have cared less about her.
After that she had to spend all her weekends there and act as a substitute. (To everyone's chagrin)
Renesmee always tried to out do her mother buying her expensive things while letting her (in a subtle way of course) know she wasn't good enough. She wasn't her daughter after all.
She never liked the Cullen's house it was to...
Clean, unmoved, hollow, perfect.
How she hated that word perfect.
Hated how they acted as they were perfect, like they could do no wrong.
But they had, they killed people and then thought everyone should forget it and move on.
It was only one word she hated more,
Destiny she was her mothers daughter after all.
Hated how it fucked up everything.
Just like imprinting.
