I remember really worrying about this episode, because at the end it looks as though Gilligan might have been killed. This had to do with the broadcasting in my area; Gilligan walks off a cliff. There's a brief shot of him hanging onto a branch, but nothing of him climbing back up. For some reason, the last scene with Gilligan and ape didn't get shown the firast couple times I saw it, and I wondered what had happened.

I'm glad that's been cleared up for you.
