Oh man, I know! "Actually, the relationship you are supporting is based off an attraction toward a microscopic egg inside Bella's reproductive organs."
I want there to be an alternative version of Breaking Dawn where Bella tells both Edward and Jacob off for being control-freaks, she goes to college, becomes a bio-engineer and eventually cures cancer and AIDs while marrying an activist and adopting five children from abusive households.
Or maybe one where she just tells them off and goes to college and DOESN'T GET MARRIED AND HAVE A BABY AT 18.
