More the originals than vampire diaries, but I couldn't find that under the categories. 100% Klaroline. Klaus saved Caroline from a pack of werewolves. Previously posted on Tumblre.

An idea of what could happen during 5x22.

Caroline gets jealous and Stefan wants to know why. Happens after 5x20 Elena and Stefan didn't get taken by the travelers.

When the travelers take Stefan and Elena, Damon and Caroline come to their rescue. Set after 5x20

When Tyler shows up to the Salvatore residence drunk and angry it doesn't end well. Caroline needs to get in contact with Klaus, who promised to leave her alone forever after their shared kiss. Will he come to help her? Steroline/Klaroline. I guess you could take this as friendship or romance, just your way of looking at it. (As of now, completed)

What I think happened with Ron & Hermione during the Deathly Hallows.
