Do আপনি think Damon and Stefan will find out that Katherine is back in the season? If so how do আপনি think it'll affect both Damon and Stefan?

I don't think Katherine will be back as in season 1, Emily already broke the spell so there is no reason why Katherine will be back.

If Katherine is back, then i think that Damon will try his best to get back to Katherine and Katherine will try to get back to Stefan. Think so.. Not that sure though..

But i'm 100% sure that Katherine will not be back!
