What kind of role do you think Rosalie played as far as Renesmee is concerned?

A loving and devoted aunty, someone who'll have a special bond with her, and do anything for her because its the closest she'll ever get to having a child. <3

i think she played the role of kind of a segundo mother kind of thing because she is always there for her.

I think Rosalie definitely plays a large role in Renesmee's life. I'm sure Nessie thinks of her as a very sweet aunt who spoils her, gives her much attention, and is very near and dear to her heart. Unfortunately, I don't think Nessie will ever think of Rosalie as her 'second' mom. I know Rosalie wishes Nessie was her own, but she sadly knows she will never be her child. So I guess to sum things up before I start to rant, as usual, I believe Rose plays a huge role in Nessie's life but will never be a big enough of a part as Rosalie would like it to be.

Does that make sense?

Probably the favourite aunt, who she can go to for all the awkward stuff
e.g boys, sex, smoking, if she wants stuff to change, when she gets annoyed at Jacob's clinginess :)

An aunt that can act like a segundo mom to Renesmaee and just laugh and have fun with her.
