Ok. Ending reveal! If you gas him, He dies, but mask is still controling his body. It gives you last chance to open it, if you do it, he gives you a tip that will lead to your death. if you open it for him , he gives tip to go to the SCP AI as he controls the facility gates, you can also gas him a bit and stop,then he thanks you for not killing him, if you open the door, same, good tip.
