I Tivo'd it and soon as I saw your post went to check it out, I usually get to my recordings on the weekends but "tickling" got my attention!
I didn't see Kevin ticking her, he had her screaming from the balloon popping and showed a clip from last week when he was behind her and was popping a balloon with his body pressed on her. I can see where quickly that looked like he grabbed her hips and tickled her.... but he didn't, she was screaming in fear.
I imagine the balloon popping fetish people went nuts seeing that. lol.
