The Vampire Diaries is a show that asks its viewers to suspend disbelief when it comes to vampires, werewolves, ghosts, and hybrids — and we happily do so! But that doesn’t mean there aren’t things about the show that irk us with their irrationality. What were the biggest logic fails in Season 5, Episode 14 (“No Exit”)?

College commuting

We know we’ve harped on this before, but couldn’t this have just put Whitmore College in the town next to Mystic Falls so we didn’t have to roll our eyes every time these characters pop back and forth. It’s supposed to be two hours away, but Elena and Caroline are always flitting back-and-forth like they can apparate or something.

World’s fastest mechanic

We really want to have faith in the random mechanic on the way to Nowheresville, Virginia, but there’s no way they would have a) had the part needed for Stefan’s classic Porsche or b) have finished so quickly. If it was that simple, why couldn’t Stefan have just fixed it himself? (Disclaimer: This could be more of a car knowledge fail on our part than a logic fail on the show’s.)

Supersonic hearing fail

How did Stefan not hear Katherine’s convo with Enzo? We know showers are loud and television spies use them to tell secrets, but we didn’t know they could cancel out vampire supersonic hearing. Hotel room walls are thin, Stefan totally would have heard this. On the other hand, we suppose TVD has to sometimes pretend vampires don’t have supersonic hearing or there would never be any successful scheming on this show. And that would be sad.

Salvatore chain is the best kind of chain

Why do the chains Stefan uses to keep Damon secured in the Salvatore dungeon at the end of the episode hold, but not the farmer chains Enzo uses to bind Damon to a chair? Our only explanation: Plot contrivance. Or the Salvatores ordered away for the special vampire cannibal-strength chains from Supernatural Supply.

Dr. Wes’ lousy experiment

Were we the only ones who thought Dr. Wes’ “experiment” was totally lame? What exactly was he trying to gauge by locking Damon inside of a house with Enzo? How long he could not eat him? What purpose does this serve? Apparently, not a very interesting one because Dr. Wes didn’t really seem to be paying close attention. And he let Enzo out before Damon could eat him for real. It just didn’t seem like a very controlled experiment is all.
