Read the summary of the penultimate episode of The Vampire Diaries season 4, cheekily titled “The Walking Dead.”

We’re getting close to the end of the season now, and if the title of this episode is anything to go by, it sounds like Silas’ plan is working out and he’s actually going to raise the dead!

Read the short summary released for this episode by The CW for more clues about what’s happening:

As Graduation Day approaches, Caroline (Candice Accola) tries to distract Elena (Nina Dobrev) by focusing on simple tasks like sending out announcements, but Elena won’t be swayed from her new obsession. Sheriff Forbes (Marguerite MacIntyre) calls Damon (Ian Somerhalder) and Stefan (Paul Wesley) to the hospital, where someone has been attacking patients. Still trying to force Katherine (Nina Dobrev) to help her, Bonnie (Kat Graham) refuses to give up on her plan to defeat Silas. As a violent wind storm causes a power outage in Mystic Falls, ghosts suddenly appear – some with good intentions and some bent on revenge.

What could Elena’s new obsession be? And notice that Katherine is still around – that’s very interesting! Bonnie seems to have changed paths and is now trying to beat Silas rather than help him… and it seems like the ghosts are back! Will Matt be able to see them?

This episode of The Vampire Diaries will air May 9. But tonight we get another new episode, 4×19 “Pictures of You,” which airs at 8/7c on The CW!
