In the end of Breaking Dawn Bella holds Edwards face and does a shield thing, what is she exactly doing?

She is pushing the shield away from her mind so that it isn't protecting her any más and Edward could then read her mind.

She is pushing her shield from her mind so that Edward can read her thoughts but Edward keeps besar her so she can't concentrate.

Bella is extending her shield, so Edward can read her mind. She doesn't need to actually touch Edward, mainly because her shield is mental, not physical.

Love, _Team_Jacob_
