A weak cop-out, which I see far too often in movies and TV shows, is when somebody shows up unexpectedly to save the hero. This is lazy writing, because it generally means that the writers can't think of anything else. How many times have you watched that same tired old scene, where the hero is saved by the intervention of third party, who usually shoots the villain?
So the problem I had in writing the Super-Sam sequence below, is how can Sam save himself against a powerful foe, when he's weak as a kitten, can't fly, and is inches from death.
I'm afraid you're going to have to wait until next Tuesday, when my solution will be posted on the Forbidden Planet Blog.
