Damon and Stefan successfully bring Elena's humanity back. How so? By pretending to kill Matt, who was secretly wearing Jeremy's ring.

But Elena positively lost it upon thinking he was dead. So welcome back!

Elsewhere:

- Rebekah agrees to help Matt study so he can graduate, as these two grow a lot closer.

- Bonnie and Katherine arrived a deal: if the latter gives Bonnie the tombstone, the former will talk to her powerful ancestor and give Katherine the power to live forever.

- Elena ends the episode by saying she wants to kill Katherine because she's responsible for everything that sucks.
