At least Marble Pie will get a chance in the spotlight in the upcoming Issue #86 of the Friendship is Magic comic books scheduled for January 2020 (https://www.equestriadaily.com/2019/10/my-little-pony-friendship-is-magic-86.html). And there is still hope that Marble Pie will find her happy ending in the Season 10 comic books scheduled for April 2020.

Both Marble and Limestone deserve happy endings. Hopefully they will in the Season 10 comic books.
In my mind.
This has nothing to do with EQG.
both are nice.
Oh, Limestone? Eh, screw her.
