Omid dies and there is literally NOTHING you can do to change it. I'm not going to say that they shouldn't; it's too late for that. I just think that they could have done some interesting points to make choices that we were all sad to not see.
I'm thinking that there should have been some variation as to how Omid could have died.
Forget the gun and leave it: The default (mandatory) one. Michelle comes in and takes the gun and shoots Omid when she gets spooked by the door.
Bring the Gun: Clem bring the gun and struggles at the experience of holding someone up. Michelle tries to get the gun and Clem gets into a Quick time event trying to point the gun at Michelle. Omid runs in and spooks Clem, making her loose grip and Michelle knees her, making Clemintine shoot Omid by accident. Clem drops the gun and Christa runs in and catches Michelle with the gun.
If they had done something like this, it would have been a real choice to bring the gun or not because of having Omid's blood on the player's hand.
For the rest of the season I understand that there are some things we can't change. I'd just like to see some effort to allow us to fight the inevitable and maybe make it worse by doing so.
