AU where everything is the same, only Duck Guy spends the entirety of Episode 4 in a state of trauma-induced shell shock after being reminded of "Time".
In wakey wakey, also known as Dhmis the movie, you can see the duck guy alive, so that means no one can die, and if they die, they randomly magically reappear in another moment.
Actually, chances are, Duck probably has chronophobia? In the It's Nice That interview, when asked what happened after time, Duck just repeats 'time' over and over again. ...And then there's this scene, so. Source: The DHMIS wiki.
