Klaus and Hayley

The relationship between Niklaus Mikaelson and Hayley.

Season Four
They meet in Tyler's house after Hayley decided to visit her friend Tyler. Hayley immediately recognized him as an Original and didn't bother to hide her dislike for the Hybrid. Klaus didn't seem happy with her open distaste towards him but, since he wants Caroline and Klaus speculates she and Tyler had a one-night stand, it can be assumed he will try to use her to break apart Tyler's relationship with Caroline.

After Dean's death, Klaus is upset by Dean's failure and Connor's death but Hayley tells him he should have had Dean use force instead. Later that night Hayley covers for Chris saying she let Elena out. Hayley also tells him if he wants to kill her go ahead, that she'd rather die then end up like one of his hybrids.

In Bring It On, Klaus saves Hayley from a rogue vampire and it is revealed they have a pact; information on Katherine in exchange for safety from her minions. Hayley goes back to Klaus' mansion with him and looks at all of Klaus' paintings, and takes a liking to a certain one as it's 'twisted'. Klaus tells Hayley he wants information on Katherine. She says she may tell him something, suggestively. Klaus pushes a piece of hair from her face and starts kissing her. They begin stripping and kissing agressively. Sex implied. In a later scene Hayley is seen strapping her bra back on. Klaus tells her he knows something about her family as he notices a special birth mark on her back. Hayley seems intrigued.

Trivia

 * Both Joseph Morgan (Niklaus Mikaelson) and Phoebe Tonkin (Hayley) have been casted for the upcoming TVD spin-off, The Originals, as the male and the female leads, so it can be assumed that their characters' relationship will evolve (not necessarily romantically) as they interact, granted that the series gets picked up.
