As a visual, this is the face that JJ was trying to use to intimidate Kris with:
Yeah, I can see why it didn't work. LOL
In any event, way to go Kris. This was like Taming the Shrew, or "Taming the Bitchy Ice Skater." Alex never got to see JJ's bad side because he always acted like an angel around him, Tony let JJ be a total bitch because he knew that's what JJ needed, and Zanie and JJ were too much alike to ever actually challenge each other.
I also liked that as bitchy as JJ was in this chapter, as soon as the light was on him, he went into performance mode in his duet with Travis. It was also a nice "continuity yay!" moment, because it was established during Brad and Robbie's wedding that JJ is a decent singer. Probably not to the level of Travis (which would probably added to his annoyance), but he wouldn't have had anything to be embarrassed about when it came to singing.
