NATALIE: Now that Katherine is entombed and Elijah seems to be doing his job, Stefan and Elena will take a romantic trip to her parents’ lake house. “They just want to be a normal couple that goes on vacation,” Paul Wesley says. (What could possibly go wrong?) “Of course, danger is pursuing them.” Not only that, they’ll have a capital-T talk about the logistics of a vampire-human relationship, Wesley adds, and the options aren’t attractive.
