i tink.... wther she is a Hale or Cullen,it really doesnt matter to me as i luv her as wat she is in e character & i tink nuthin change dat... i tink ppl here will prefer her to be e Cullen instead of Hale..izzin it..?
Technically, she at first was a Cullen then when she met Jasper...she shortly became a Hale. Just like Rosalie and Emmett. Also it seems like the Hales are more agressive then the Cullens. I don't see Alice as being aggresive.. you know her always reminding Jasper "you won't hurt Bella!!!"
