“The Vampire Diaries”: We’ve seen the Salvatore brothers during the Civil War, and now we’re heading back in time once again — to World War II. This time, it’s Stefan who goes into battle … and yes, we will see him in uniform. And yes, he looks as good as you’d imagine. Speaking of flashbacks, we’ve confirmed exclusively that Scottish actor Paul Telfer will play Alexander, a vampire hunter in the 1100s whose encounter with Rebekah reveals quite a bit about her character.
