I agree, the removal of the scene with the gun ( and the choice you could do at that point ) in the beginning feels very weird as in v4.5 that scene (and the choice you made) felt really important for the MC psyche.So... the dev removed the intro scene with the gun... I think that was very important to let us see the character of our MC, to see his starting point and his later development... If he removes it, I think it will make our MC much more bland and just a typical introverted MC... Can't say I like where the game is going.
And it also had an impact on the woman reaction later when she meet the MC again that could go very differently if you let the gun go or shot it on the ground near her.
