THE TRUTH CAN BE VERY, VERY DEADLY — Elena demands that Stefan explain the frightening events that have been happening in Mystic Falls. In a string of flashbacks, Stefan explains how his rivalry with Damon began back in the Civil War when they both met the love of their lives, Katherine, the vampire who sired both of them. In the present, Damon impulsively takes control of Vicki's future, and a confused and terrified Vicki runs away.

- Stefan explains to Elena the reality of vampires and its differences from the myths.
- Stefan and Damon's childhood home is seen for the first time in the 1864 flashback and the ruins of the house are seen in 2009 as this is where Stefan hid Damon's daylight ring.

- Damon tells Stefan if he doesn't return his daylight ring, he'll hurt Elena.
- Elena asks Stefan if he ever compelled her. He tells her no and points to the necklace that he gave her in Friday Night Bites, stating that it protects her from compulsion. Stefan tells her he gave it to her both to protect her from other vampires and also so he wouldn't be tempted to compel her himself.
- This is the first episode where someone other than Damon is functioning as an antagonist; in this case, Logan Fell was the antagonist, acting as an extension of the Founder's Council.

- Vicki is the first vampire to be seen being turned by Damon's blood in the TV series, though chronologically, it was not the first vampire he has been known to have sired; that title goes to Charlotte, who Damon turned in the 1940s when he was living in New Orleans.
- This episode marks the first time it is demonstrated that vampire blood can heal a human's wounds, as all of Vicki's bite marks disappeared after Damon fed her his blood. Though Damon didn't heal Caroline's wounds from his feeding from her ending up with Caroline having to wear scarves to cover up the bite marks.
