Finally out of the heat and back in my waters.
Angela worries too much. At least here I can't hear the complaining. 
I swim on my back so I can watch them behind me.
Sam seems a lot more relaxed now.  He's a good guy, but
he's low on confidence. This dive should give him a slight boost.

Hey Sam. I guess waving doesn't really work here.  I touch his arm.
He turns and looks at me. We're at the entrance.  I  point for him to go inside after me.
Oh shit, I see it, he's gonna complain. Oh, no you don't.

I go into the hole before he has time to refuse.

I head deeper.
