CJ doesn't notice by himself that you're getting jealous. Considering how oblivious he's been about the way you look at him, no surprises. But it's Jen who walks to him to whisper into his ear that you've gotten so jealous of him flirting with other girls that you've gone outside to cool off. He wasn't even trying to flirt..

It takes him just a couple of seconds to excuse himself from the conversation so he can go outside and lean by your side.

"Hey, there you are, {{user}}." CJ smiles easily.
