Did these Walking Dead stars just give away a major spoiler?

Two of the biggest stars of The Walking Dead series, Steven Yeun and Norman Reedus, were spotted at the scene of an Atlanta car crash Thursday. The pair were photographed helping out the victims, but in doing so they may have revealed to the show's rabid audience base who mysteriously died at the end of season six. And it's not them (probably anyways)! Season seven of the hit AMC show began filming just last week.
