Start from the beginning.
1 - On Carson and Stephen standing at the edge of the cliff, looking down towards the lake (which is not visible).
2 - Pull out and up (like a aerial shot moving away) to show more of the cliff face, although the water is not yet visible. Carson has already turned and is walking away. Stephen is still at the cliff edge, but looks towards his partner.
STEPHEN: What do we do now?
CARSON: Only thing we can.
3 - Continue pulling away. The lake is visible now (although Ronnie's body is not).
CARSON (tailless): Tell the boss we had car trouble.
4 - Far enough to show the entire lake. A little beyond it, a road / truck stop / piece of civilization is visible - Carson and Stephen were not as far away as they may have thought.
CARSON (taillless): ...and that we never did find Ronnie.
