Vampire Diaries star Ian Somerhalder (Damon Salvatore) is feeling the love in his recent tweet about the show’s 100th episode, thanking fans for their “amazing” support. No, thank you, Ian. But what had us especially interested in his tweet was the snapshot he sent along with it: a first glimpse at Damon in the much-anticipated 100th episode!

“100 fricking episodes! Huh? You're all so amazing-thanks 4 this insane spaceship ride. I truly thank & love you. Love IS & DS,” Ian tweeted on November 9, along with a snapshot of Damon in Season 5, Episode 11, aka the 100th TVD episode! The photo doesn’t give us much to go on. In it, Damon is looking gorgeous (per the usual) and concerned (often, quite common these days on TVD). What might be causing the vampire’s gorgeous brow to furrow?

Well, Ian himself mentioned that this is going to be a big episode for Katherine. He told ETonline: “We learn a lot about Katherine, which has been a very intense part of the story. Stefan, Damon, and Elena all have a very different way they want to deal with her. Damon just wants her dead as a doornail, so it’s interesting.” Could that be inner conflict on Damon’s pretty face?

Or perhaps, he’s worried about an impending death(s). According to executive producer Julie Plec, “Death is knocking at the window” in the 100th episode.  Yikes! Is Damon metaphorically listening to that metaphoric knock? Knowledge of a loved one’s impending doom would certainly explain that frown.

Why do you think Damon is frowning the 100th episode? Sound off in the comments below!

The Vampire Diaries airs on Thursdays at 8 p.m. on The CW.
