What's Caroline Doing To Klaus? Photos for Season 4, Episode 18

Caroline in Vampire Diaries Season 4, Episode 18, “American Gothic”
And here we thought the big story would be Katherine’s (Nina Dobrev) and Elijah’s (Daniel Gillies) return, but in the spoiler photos for The Vampire Diaries Season 4, Episode 18, “American Gothic,” there are bigger, more shirtless fish to fry.

Caroline (Candice Accola) isn’t too happy that she gets elected to
assist Klaus (Joseph Morgan), but after the OV’s run-in with Silas, boy does he need it. Trust us. There are some very provocative shots in here!
Elena (Nina Dobrev) and Rebekah (Claire Holt) head to Pennsylvania, where they meet both Katherine and Elijah. Are those two working together, or is it a coincidence?
Stefan (Paul Wesley) and Damon (Ian Somerhalder) are both worried about Elena, but she doesn’t want her emotions turned back on. Also, Stefan has his own vision for his future, which surprises Damon.
