Some of the most significant moments of The Vampire Diaries had repercussions that changed everything for the main characters. There are certain key events throughout the series that changed the course of history for everyone.
In The Vampire Diaries, Elena (Nina Dobrev) faces a major change after drowning with Damon’s blood in her system. After a moment of wondering if she would survive the transition, Elena completes her transformation into a vampire.
With heightened senses, intense emotions, and the father bond, there is a lot of drama surrounding Elena being a vampire. She is also a significant force behind the search for the cure.
Stefan leaves with Klaus
After spending most of the first two seasons of The Vampire Diaries being considered the good brother, Stefan Salvatore (Paul Wesley) has a chance to show the dark side of him.
Stefan’s Ripper and Humanityless Sides are explored during Season 3. But it also generates more drama in the love triangle between Stefan, Damon (Ian Somerhalder) and Elena.
Kill an original
When an original vampire dies, his entire line of parents dies with him. The group originally learned this when Finn died and then used it to complete the Jeremy’s Hunter brand.
The brand grew every time Jeremy (Steven R. McQueen) killed a vampire, so when he killed Kol Mikaelson (Nathaniel Buzolic) and therefore all the vampires in his line, the brand completed itself.
It also becomes an essential reason why the group cannot kill Klaus Mikaelson (Joseph Morgan) in The Vampire Diaries as they come from his parental line and aside from that the story serves for The Originals.
