Cas is strong as crap, so Dean finds himself in the water pretty quick. He has a little more time to prepare than Cas, but he still comes up sputtering. That was still hilarious though, and he grins at Cas as he relaxes in the water.

"What? You said you wanted something happier. I'm thrilled. What about you?" He splashes at Cas lightly.

This is... really what he needed though. Hell still burns fresh and hot, and he wants to get rid of those crawling thoughts, that edge of fear and pain still holding onto him. This place was a good idea, mood-wise, but he's not sure sitting still and fishing would really do anything to calm him.

Watching Cas look like a... drowning accountant is a bit better.
