We’ve heard a lot of things about The Vampire Diaries 100th episode (“500 Days of Solitude”) — how “death is knocking at the window” in Mystic Falls, and that Caroline does something “scandalous,” and to expect a few “familiar faces” — and now Kat Graham is adding fuel to the fire with this latest spoiler.

“I definitely think the fans are going to lose their minds,” Kat Graham told a group of reporters on the set of The Vampire Diaries in Georgia. “I think the fans are going to be in ecstasy when they watch it… There are some things that happen in the 100th episode that are going to make a couple people stand on their couches and scream at their TV, ‘Yes, yes, yes!’”

What could Kat be referring to? Our best guess is Klaus and Caroline’s much anticipated reunion in the woods. In the minute-long promo, Klaus runs unto our favorite vampire Barbie in the woods, and surprisingly, she looks pretty relieved to see him. There’s also an Australian promo floating around the internet that shows Klaus and Caroline kissing, and more importantly, Caroline is the one initiating the kiss. So we know where this encounter is heading.

If this fan favorite couple does end up sealing the deal with a kiss, we’ll be among the many fans standing up on our couches and screaming at our TVs — because these two are so meant to be. (Also, does this mean Kat Graham is a Klaroline fan? We love her even more now!)

Of course, Kat could also be referring to Nadia’s plan to save Katherine. Think about it: the thought of Katherine Pierce dying in Season 5, Episode 11 makes us so incredibly sad. So, what if Nadia saves the day and finds a way to save her mother? OK, so maybe that isn’t so likely (given these spoilers), but we’re going to be optimistic about this one.

Then again, the thought of seeing Aunt Jenna (and possibly Alaric?!) in the 100th episode is reason enough to make us giddy. And, the heartfelt moments between Stefan and Elena are just the icing on this celebratory cake.

What moment do you think Kat is referring to? Is there a moment you want to see in tonight’s roller coaster 100th episode? Sound off in the comments.

 Catch the next episode of The Vampire Diaries on Thursday, January 23 at 8 p.m. ET on the CW.
