think about it:
>comic arc happens before season 4 starts
>writers are avoiding any conflict with the show, pretty sure they will make it end in a way Celestia will never be able to see Godd!Sombra again.
>the last chapter summary is very suspicious: “someone will have to make a sacrifice to save the day, but who?”
Hes in another world that after the arc it will be likely sealed (hence the mention of a sacrifice to save both worlds.) so they can never visit it again.
