In the last episode of 'The Vampire Diaries' before the mid-season hiatus, "O Come, All Ye Faithful," the group of supernatural beings in Mystic Falls was forced to deal with hybrid Tyler's (Michael Trevino) plan to get rid of Original Hybrid Klaus (Joseph Morgan) and Jeremy Gilbert's (Steven R. McQueen) desire to kill his newly fanged sister Elena (Nina Dobrev).
Despite his best intentions to unsire all of his fellow hybrids from Klaus and then defeat him, Tyler's friend Haley ruined his master plan with a plan of her own involving the slaughter of 12 hybrids. In his rage, Klaus decided to take out his revenge on Tyler by murdering his mother, Mayor Lockwood (Susan Walters).
Over at the Gilbert cabin, Bonnie (Kat Graham) and Professor Shane (David Alpay) tried to help Jeremy overcome his intense desire to kill his sister. They decided to invite Elena, who brought Damon (Ian Somerhalder) along, to come over and help with the process. Although it failed at first, the process gave Elena hope that Jeremy could eventually overcome his urges.
In the upcoming mid-season opener, entitled "After School Special," Klaus' sister Rebekah (Claire Holt) returns to Mystic Falls and gets on Elena, Carolina (Candice Accola) and Stefan's (Paul Wesley) case about finding the cure of vampirism. Meanwhile, Bonnie's dad Rudy Owens (Rick Worthy) takes up the role of Interim Mayor following Mayor Lockwood's death and decides he wants to take a bigger role in Bonnie's life.
At the Gilbert cabin, Damon and Matt (Zach Roerig) help Jeremy hone in his vampire hunting skills, but their progress doesn't sit well with Klaus.
'Vampire Diaries' S4E10, "After School Special," airs Thursday, January 17, 2013 at 8 p.m. EST on the CW.
