Elena shouldn't take the cure but maybe go and live with Jeremy while vampire hunting. Or body jump into a human like Rebekah Mikaelson. There has go to be a empty body in a coma. She can be Elena on the inside but a possible blonde on the outside. She can move into a body that may look like her. For example, Victoria Justice or the curly blonde girl from the show Twisted on ABC Family Channel. I just hope the ending will be good and leave her character open.
