vampire diaries season 4 episode 10 after school special

so last night to say episode 10 of the vampire the diaries was a shocker Rebecca is back...
bad news for everyone it looks like especially for Elena, Rebecca has Elena under compulsion so she has to tell Stefan how she really feels about Damon, which tears Stefan apart after hearing her confession. Caroline begs Rebecca to stop but she doesnt.. Tyler comes into the picture and Rebecca compels him to turn, knowing that he will kill all three of them but, she doesn't care... turns out that Stefan wants Rebecca to erace all memories that have to do with Elena but, she won't says its to easy and, now he has to see what its been like for her for the past 900 years. seems like Stefan hates Elena at this point he has made a proposition to work with Rebecca to get the cure to be human says they both hate there brothers and Damon swears to elena he will get it for Elena to make her human again. While all professer Chain cares about is raising cylis from the dead and all his evil seems like season 4 is going to be very interesting...
