Damon and Elena work up a plan to get rid of Klaus for good. They want to lure Klaus back to Mystic Falls for Mikael to kill. Elena ends up staking Rebekah. Everyone goes to Tyler's house. Since Mikael is not allowed in, Damon has to be the one to kill Klaus. At the party, Klaus tells Stefan to go get Mikael's dead body. Stefan goes to Damon and Mikael to tell him that he's no longer part of the plan. Mikael feeds on Stefan.
Mikael shows up at Tyler's house and taunts Klaus about being alone and a coward. Mikael threatens to kill Elena if Klaus does not invite him inside. Klaus counters this by saying he can get his hybrids to kill Mikael at any moment. Klaus doesn't believe Mikael would kill Elena so he eggs him on. But he does. Damon knew about this part of the plan so Elena was actually Katherine. Unfortunately, Katherine was in on the plan as well. Damon goes in for the kill when Stefan jumps in and stops him, leaving Klaus free to kill Mikael.
Klaus has ensured that his death means the death of Damon as well. In order to save Damon, Katherine and Stefan both confess that they still care about their loved ones. Damon and Elena finally agree to let Stafan go. Katherine and Stefan plan to get Klaus back for everything by stealing Klaus' entire dead family.
