E!Online chatted with Paul Wesley about what’s ahead for Stefan and Elena, including a “heartbreaking” conversation, and the return of Stefan from seasons past. Plus, will Stefan be getting a new love interest in the love triangle swings in Damon’s (Ian Somerhalder) favor?

In last night’s episode, viewers saw Stefan begin his battle with moderation, with Damon leading the human blood drinking-train. “[Damon] tries to become that sort of mentor in a way in getting Stefan off the path of extremity and teaching him moderation,” Wesley teases. “It all kind of comes to a head and it doesn’t work out too well.”

Though Stefan will not have an easy time with it, Wesley says the process will lead him back to Elena. “The more he deals with moderation, the closer he grows to Elena. He was so involved in his own darkness, he didn’t have any time for romance. As the episodes progress, the audience is going to see Stefan maybe becoming more like he was season one and two, sort of the romantic lead hero.”

Still, Wesley stresses that Stefan will always have that dark side ready to consume him at any moment. “What’s really important is to make sure that Stefan always has a flaw and that he always has that potential darkness because I think the minute we make Stefan the same Stefan as season one, it becomes a little predictable."
