We’ve seen the kind of damage Dr. Wes can cause (R.I.P., Jesse), but not against one of our beloved Vampire Diaries main cast members! In tonight’s episode, Dr. Wes will be turning his scapula on Damon (Ian Somerhalder), but it looks like he has Elena (Nina Dobrev) in his clutches in next week’s mid-season finale.

TV Guide has a seriously chilling promo pic (click here to see it) for Season 5, Episode 10 (“Fifty Shades of Grayson”) that shows Dr. Wes stabbing Elena with a needle, the college vamp writhing in pain. Yikes! Could these be a continuation of the torture scenes Nina had trouble getting through on the set? Either way, things are about to get pretty intense for our freshman vamp.

Luckily, the Salvatore bros are on the case! According to the episode synopsis, “Damon realizes Elena is in danger and enlists Stefan’s help to find her. The brothers pay a visit to Aaron, and Damon shocks Stefan by revealing his first-hand knowledge of Aaron’s family. In an attempt to stop Damon, Dr. Wes unleashes his secret weapon, forcing Damon to deal with a part of his past he thought was gone forever, as well as the consequences of his decades-long plan for revenge.” Yep, sounds like a midseason finale to us!

Does anyone else think Damon was the “bear” that killed Aaron’s parents? Perhaps as part of this revenge scheme he’s apparently been concocting. And how does Elena’s father play into all of this? The episode is titled “Fifty Shades of Grayson,” i.e. an allusion to Grayson Gilbert. Is it possible that Damon was the one who caused the Gilberts car to go off the bridge and into the river the night Elena’s parents died? If Damon was trying to get back at Augustine Society members for his time as an Augustine vampire lab rat, it seems possible. And heartbreaking, given the importance of Elena in Damon’s life now…

What is Dr. Wes doing to Elena? And what secrets is Damon hiding? Sound off in the comments below!
