Personally I think going into Civil War without watching at least Winter Soldier and Age of Ultron would be a mistake but that doesn't mean she won't enjoy it just you will be thrown in the deep end expecting to know who this characters are.

You could always tell her the basis of the them two if she wants to watch CW2 first, although Ultron has a fair bit of Iron Man in it so I just let her watch all 3, WS up there with the best super hero films.
