"The Vampire Diaries" season 4 will continue next week with "The Rager," episode 3, which will introduce a new character in Phoebe Tonkin's Hayley, and in an interview Entertainment Weekly shared Thursday, Julie Plec addressed what she could mean for Caroline and Tyler's relationship.
Hayley is the werewolf who helped Tyler break the sire bond to Klaus last season, so Klaus isn't exactly going to be happy with her either—if he knows that who's she is, of course. Either way, he'll see her as someone he can use to try to get between Caroline and Tyler (he's not over Caroline, and we have to admit, we like seeing him pursue her even though we would never want to see anything happen—Klaus is still Klaus). According to Plec;
"The expression of glee that Klaus gets on his face when he realizes that Tyler might have been holding this as a secret from Caroline is priceless. Klaus is up to no good for a good portion of this season. He’s not on his best behavior. But watching him try to drive a wedge between Caroline and Tyler with just the control of gossip is actually superfun. Of course, Tyler is gonna have to try to take back that power and save his relationship and convince Caroline that she can still trust him."
We can't wait to see how this plays out, but considering what Caroline and Tyler have been through, they deserve to have some time together—and to be happy during that time. It seems like they're always being interrupted by some sort of danger or some kind of drama, and that's just going to happen once more with Hayley in time. But what will Tyler be keeping from Caroline about his experience with Hayley? Is it as bad as Klaus is hoping so he can use it to his advantage? We would think that Caroline would be at least a bit grateful to Hayley since she helped Tyler break the bond, but is there more to the new werewolf in town than meets the eye? That's what we're expecting because this is "The Vampire Diaries" after all.
In the end, we expect poor Klaus (at least in this regard) to once again lose out and for Tyler to fully explain himself to Caroline and keep her from being too angry about anything he may not have told her. We'd also like to see Caroline and Hayley bond at a certain point (though we don't know how likely that is) if only to see Klaus' reaction once he learns that his plan to get between the vampire he wants and the hybrid she loves isn’t working.
