Ok so i finished the game twice. one i saved doug and the other i saved the lady.
So the point here is that in one I gave the lady the gun to kill herself, and she did. It was cool. The other I didnt give it to her, we fell and she shot herself and zombies came after us.
when we are done with the episode i thought we couldn't go back to the motel because of the incident and the place was overrun by zombies. But we still went there.
And in the first it was Ok to go to the motel as we killed all the zombies there and no zombies came after us when she shot herself.
so it didn't matter if we gave her the gun or not, when it should have
Edit: Sorry about the title, supposed to be "A decision that should have mattered but didn't"
