The Vampire Diaries dug up a few plot holes on last night's "Break on Through," but the episode did at least conclude with a new/old mission for Damon and Stefan:
All-out destruction of The Originals. And they now possess the weapon to finish the job. Look for the Salvatores to bring Elena, Caroline and Matt in on their plan next Thursday night.
What else can fans look forward to on "The Murder of One," the final TVD episode before another two-week break? Bonnie will respond to a threat from a returning Klaus by working on a spell he demands; Finn will make another appearances; and Stefan will encounter danger with Klaus and heartbreak with Elena.
