[This is probably not real. I got this idea in school]
In episode 5, let's say that you found clementine and her parents. Her parents think that you're the bad guy. When they first see you, clementine's dad pulls out his gun and aims at Lee. Lee notices and quickly pulls out his gun and aims at Clementine's dad. Clementine's dad shoots but misses. He starts reloading and Lee knows that there's no stopping him by talking.
So what would you do, let clementines parents kill you, or would you kill them?
[if you let them kill you, you wont be able to make choices, but you will see how things turn out]
