S02EP25-6 - "A Canterlot Wedding"

[Lerian]

Idea for a possible situation?

So the changelings have won! Huzzah!

If by force, the ponies now under their control are bitter, suspicious and resentful. This inhibits their ability to risk loving new ponies and taints the existing love they give with paranoia.

If by stealth, (Twilight didn't discover them for whatever reason), the changelings are now in and feeding but the ponies they feed from begin a slow decay to not loving. Their changeling partners don't return the ponies love and relationships break down ending up in a situation similar to above in the long term.

Chrysalis is then able to whip Cadence out of the mines and use blackmail (look at these ponies dying) or reward (You can have a week out of the caves) to get the ponies loving again.

Cadence is 'love fertiliser' for their pony crop....

Sadly, they did not postpone move the excitement to night fall, then Luna wouldn't have missed anything! She did not know her sister had been overpowered by the Changeling Queen. It was nice to see her coming for the night watch. How could she and her sister not know that the false pony was already inside Canterlot?

Overall, the two episodes are great.
