Why did Ross change the sound-effects on the guns? Did he do it based on his conversation with Nojah and Sarahon about editing minecraft sound-effects? I mean I know he explained it and that Daniel was the one to do it, but why would he decide now would be the best time to change it after almost 50 episodes?
He's gone back to using the normal sound effects.
In one of the earlier Shephard's Mind episodes, Shephard is knocked unconcious and starts mumbling about Freeman, but at that point he didn't know that Freeman existed.
He could just know someone else with the same last name.
