Any Really Good Dark Episodes?

[EgotisticalRaven 9]

Hey, I really like the dark episodes of My Little Pony, but it can be very hard to find them, can anypony recommend any very dark episodes?

 

By 'dark episode' I mean episodes that have very morbid or strange plots. Such as 'Party of One', 'Too Many Pinkie Pies', 'The Cutie Map' and 'Lesson Zero', which are some dark episodes I've seen already.

 

Keep in mind I have not watched a Hell of a lot of MLP. It can be very hard to find dark episodes, as when I tried Googling it, nothing came up that was really helpful.

For Whom the Sweetie Belle Toils was pretty dark at certain points. I'd check that one out

Not sure. You've already listed most of the dark episodes in the show. I personally think that the CMC's nightmare episodes are pretty dark, especially Sleepless in Ponyville.
