In an episode toward the end of the season, Kurt and Carolyn were returning from a romantic date when they started kissing in the backseat of a car. Someone else was driving the car, but Kurt and Carolyn were (mostly) alone.
The only thing is, they still have a few mounted cameras pointed at them ... and Kurt turns them off. Some fans assumed that meant they hooked up, but Kurt has a much more innocent explanation as to what happened.
"We were just making out pretty intensely, and any chance I could get to get away from the cameras, I did," Kurt told Distractify. "I just didn't want cameras in my face and, you know, I wasn't sure how this thing was gonna get cut up or what they'd show. Of course [the show makes] it look like we're about to get naughty in the backseat."
