All that said, I definitely should have seen this coming. Craig Mazin (the showrunner) has a great podcast episode from a few years ago where he basically gives a masterclass on writing a screenplay, and I learned more from that single episode than just about any book I've read on the subject. I took detailed notes, I just went back and found them, and here's exactly what I wrote down, word-for-word, for the climax…
Quote:
The protagonist has to prove himself. Defining moment. His or her worst fear. His or her greatest challenge. It will resolve the story and the protagonist's life. Design a moment that is going to test the protagonist's belief in the theme. The protagonist has to prove his or her new belief. This is where the protagonist literally embodies the point of that idea with everything they have.
Tempt the protagonist with a relapse. Torture the protagonist one more time. Hold that safety blanket up and say, go ahead and go back to the beginning. I'm giving you that thing you wanted on page 15. To return to your old life. But the protagonist has to reject that temptation that you designed. Acceptance of theme through action. The protagonist has to act. Give them the opportunity. Has to act in accordance with the theme. Rejects the stasis.
Which is exactly what Mazin does with Joel. Designs a moment to test Joel's newfound belief in love. Then temps him with a relapse, i.e. a life again without Ellie. In other words, Joel is given the choice to go back to who he was before, the Ellie-less version of himself he was comfortable with when we first met him. But instead, Joel chooses/proves his love - his new belief - by accepting the theme through action (mowing down the Fireflies and rescuing Ellie). Textbook character development from the guy who literally wrote the textbook, practicing exactly what he preaches. Dude is so damn smart, and so damn good. And the fact that Joel's decision carries so much weight going into season two makes it all the better.
