So I've previously agreed with people (and come to think myself) that choices don't matter. The big example is Carley and Doug. But the new season raises a question: what is the criterion for 'not mattering?' With Carley and Doug people say it doesn't matter because no matter who you save, the other one dies, and they die in the exact same spot.
Seaon 2 you could save Pete, and depending on your choice he dies at the end of episode 1 or at the beginning of episode 2. Does this mean it didn't matter?
Moreover, I got Alvin killed. I didn't get Nick killed. Suppose one of them is scripted to live past the beginning of episode 3 (even onto further episodes, or hypothetically the end of the season). But what if they both (or whoever is remaining) dies in the beginning of episode 3? Does that mean the choice didn't matter?
What I'm trying to get at, are what are the criteria for a choice affecting the life or death of a character to truly matter? Do they have to die in a different spot (or in, the case of a choice, their substitute not die in the same spot)? Or, the strictest one, do they have to make it all the way to the end of the season?
