I had a really cool dream and now I'm mad that I can't remember it.

It was an ATLA crossover, I think. I don't remember what the crossover was, but there were these three people sitting on the beach of a deserted island. They were all benders, but the rules seemed to be... a bit off? One of them had been a waterbender at first, but now she was learning firebending too.

I think the other two were firebenders, although one of them might have been an airbender too. One of the firebenders went swimming, but he got caught in a current that started pulling him away from shore.

He was supposed to be... badly injured, I think? So badly injured that he couldn't use his powers very much, only for very basic things. But he wasn't actually injured- he was only pretending. He ended up using his powers to get back to shore. He did a bunch of tricks on his way, too, like gliding over the water and doing flips in the air.

The other firebender got pissed, while the water/firebender seemed more amused than anything. I wish I could remember more of it, because it was really cool :(
