WELL.........................................
no charlie never does find out but he does know Jacob is a werewolf
The cullens didn't like Bella knowing because they thought she would tell everyone and they would have to move.
no they didn't, Alice found proof that their baby wasn't a danger.
Because in the car after the restaurant, she told him that she knew and they talked about it.
Didn't you see the movie? For God's sake!
because it has to do with them all and carlisle would be mad if he didn"t
chapter 9 theory page 179 i knew that without even looking at the book
Yes and no. Charlie had a mind shield that his daughter, Bella inherited from him, but hers was stronger. He never found out about the Cullens being vampires, but Jacob shape-shifted into his wolf form right in front of him. After that, he believed that whatever he learned would be on a need-to-know basis.
She saw herself and Jasper joining the Cullens in her visions, and followed them until she found the Cullens and moved in with them, much to their surprise.
In breaking dawn, Alice and Jasper run off without telling the other Cullens to find another baby similar to Renesmee. When she has found another halfvampire, she will present it to the volturi to show them that Renesmee is not dangerous and they should not kill her.
I doubt it, since the Volturi would eventually find out, and then that person would either a. become a vampire, b. become a volturi guard, or c. be killed by the volturi.
It doesn't say in Breaking Dawn but she doesn't find out. Her mom would totally freak out if she found out.
No secret room has been found.
