Cougar doesn't exactly look like he feels bad about insulting Jake, because he's pretty sure he could say anything and Jake would know that he doesn't really mean it. Why would he want to push away a best friend who can not only translate for you, but who actually knows every small body movement and what it means.

When Jake gets dramatic and sinks himself in the water, Cougar decides to unlace his boots and hike up his pants to wade in, perched enough on a flatter rock above. When he's close enough, that's when he pushes at Jake's shoulder with a foot to tip him fully into the water.

He said he was hot, yes?

Cougar's helping, he's so very helpful. In fact, he's so helpful that he crouches on the rock with a devious smirk on his lips, waiting for Jake to surface for air.
