The episode starts with a flashback from a year ago where Mason (Taylor Kinney) is at a bar and when he leaves, a man named Jimmy follows him.
Back to the present, Mason warns Tyler (Michael Trevino) that any death that comes from his hands, even if it's an accident, it will trigger the curse and he has to be careful.
Elena (Nina Dobrev) tells Jeremy (Steven R. McQueen) about the Lockwoods because she promised not to hide anything from him anymore but she asks him to not get involved.
When Jeremy leaves, Stefan (Paul Wesley) appears in Elena's room and they plan their fight of the day so Katherine keeps believing that they are not together.
Liz (Marguerite MacIntyre) gets ready for the Mystic Falls' Historical Society Volunteer Day and wants to spend some time with Caroline (Candice Accola).
Meanwhile, Liz watches Damon from afar as he is drinking a lemonade that is full of vervain and he chokes, knowing now that Mason was telling the truth.
They carry them down to the old Lockwood slave quarters where Liz asks Mason to leave because he is not part of the Council and he can't be there after she promises that she will kill the Salvatores.
Damon feeds on the deputies and get his strength back, Stefan refuses to drink human blood and Liz sits in silence.
Liz asks to be killed but Damon does not do it because she is his friend and they take her at the Salvatore house to lock her at the basement till her system is vervain-free and they will be able to compel her.
Caroline confesses to Elena that Katherine made her spy on her and Stefan and report back to her, otherwise she would kill Matt (Zach Roerig).
Emma Fraser of TV Overmind gave an A+ rate to the episode saying that it deserves a hearty round of applause for such excellent story telling.
The rapid pace of the plot, however, doesn't create the sense that the story is rushed, because of episodes like this one, which, as a whole, successfully balances action with emotional conflict.
"[4] Matt Richenthal of TV Fanatic rated the episode with 4.9/5 saying that he didn't see coming Katherine being involved with Mason.
There was a hint of this last week when we saw Katherine in a flashback with the moonstone, but the revelation that she is pulling the strings on Mason is a surprise, and a good one.
"[9] Shannon Vestal from Buzzsugar gave a good review to the episode saying that Caroline and Mason had the spotlight on them this week and they each do a lot with their time.
