The CW presented its new primetime schedule to the world this morning. When the network returns with new episodes in September, The Vampire Diaries will remain in its 8 p.m. Thursday night time slot.

But many changes and developments will certainly be on tap for the series. Such as? The CW's official fall press release reveals some suspenseful and sexy scenes ahead on our favorite new show:

Next season, the appearance of the villainous Katherine in Mystic Falls throws a wrench into the love triangle between Stefan, Elena and Damon, and the other residents of Mystic Falls must choose sides as they fall victim to a new breed of danger. New and unexpected friendships will be forged, allies will become enemies, and hearts will be broken.

Stefan and Damon will be forced to face a villain more evil and diabolical than they ever believed possible. And they’ll take their shirts off.  Frequently.

Katherine is here to stay on The Vampire Diaries. Her presence will be felt, strongly, on season two.
