The Cure? - Spoiler from S4 finale

[windowseat]

Now that Katherine has forcefully taken the cure, once she is human again will she be able to re-become a vampire if she again dies with vampire blood in her system?

My thoughts are that she would be able to become a vampire again, but she would have to "start all over". By that I mean when she became human her necklace would have lost its daylight powers and she would have to find a witch to make her a new one. Also, she would no longer be "older" than Stefan/Damon/Elena/Caroline etc so they would end up being stronger than her. Thoughts?

I think that we won't know if it's possible or that she would just die. JP mentioned something about it being a risky proposition to attempt again just in case she can't turn again. So maybe they just really won't know and whether or not she wants to risk it would be the story there.  She just better not use Damon's blood cause we don't want any more sire bonds!

Damon & Co. should get a Witch to lock her to the town as a form of rehab/reform. If she can live the life of a human and show some decency, they'll turn her again. She wanted the exact opposite of this so she's going to be pissed but can't exactly pick a fight with Elena about it now, can she? She still shouldn't attempt it though without being sure she can turn again.
