You think you have relationship problems? Try walking a mile in the Winchester brothers’ shoes. At a recent Supernatural screening, Wetpaint Entertainment talked to executive producer Bob Singer about the sibs’ complicated relationships, what the future might hold for them romantically, and which characters will be returning in upcoming episodes!

Wetpaint Entertainment: Why is it that introducing girlfriends to Sam and Dean doesn’t go over well? Do you think you’re getting closer to finding the type of girl that could last?
Bob Singer: Felicia [Day, who plays Charlie] is going to be coming back in an episode. I don’t think there’s ever going to be a third wheel. We’re not going to have Catwoman. The feedback that we get is that it’s not something the fanbase particularly likes. We keep trying. I personally really thought the Amelia character was great and opened up a side of Sam that was really interesting, and I thought Liane [Balaban] did a terrific job, but I don’t think it’s ever going to be a three-hander. Part of the appeal is these last men standing, and that’s who they are.

Is the relationship between the brothers still on shaky ground?
I don’t think it’s shaky — I think what you’ll see in subsequent episodes is another kind of conflict between them, but it’s not necessarily, “Do I want to do this?” or, “What’s my plans beyond closing the gates of Hell?” It’s a new conflict. There’s always something going on between them.

Can you talk about who will return this season?
Kevin (Osric Chau) will be back, Benny (Ty Olsson) will be back, Castiel (Misha Collins) is back, maybe Amelia, maybe not. Every season we like to bring the season full circle and get a lot of questions answered about that season but then pose new questions for what the next season is going to be. So I think all these people that we introduced will have a payoff.  

Do you consider the Amelia arc wrapped up?
We think she’s a valuable character and it certainly creates a good complication in Sam’s life, but we’re just doing the end of the season now and we don’t have anything specific [planned].

Supernatural airs Wednesdays at 9 p.m. ET on The CW.
