That was my original thought before I heard about the comic version. I hope they will still do it.

But I do pity him. He seems to receive the worst kind of punishments out of 4 antagonists.

First not only did his body was destroyed and he was dethroned but sisters had decided to seal him into frozen darkness in the ice for eternity. He gets out only to be executed by the love princess.

Discord had screwed over the world and all he got was being turned into stone and received a chance at reformation later on. Nightmare Luna was sent to the moon for a thousand years and then brought back to the throne as if she hadn't tried to destroy the world in the eternal night.

Chrysalis if I understood correctly had got away with trying to invade Canterlot without any punishment and only when she tried to get revenge against mane 6 did she got into trouble and received a minor punishment.

I fear what will happen to Sombra in the third punishment.
