Here's my list of potential ideas for S7. I'd like to think all the good writers aren't just writing for the movie and that the writers they have can churn out something really good. (Top Bolt was a step in the right direction, but still pretty average overall) So without further ado, here's my list.
S07E01: The Anti Seven (Part 1) (Basically what I was hoping To Where and Back Again would be): When Discord finds out Fluttershy is acting grumpier than usual and is causing trouble all over Equestria turning ponies into jerks with collateral damage (like Care Bears villains only a little darker than that) he seeks to prove her innocence, only to find that the mane six are out of commission and have been replaced with evil versions of them created from their darkness, so it's up to Discord, The Cutie Mark Crusaders, Diamond Tiara, and a whole slew of reformed antagonists to save the day. (Basically the Discord episode I've been dreaming of.)
S07E02: The Anti Seven Part 2: After Fluttershy is saved by Discord, the Anti Seven trap everypony else (including Discord) in a glass sphere and reveal their master Scorpan, has betrayed the ponies and wishes to do what his brother could not. Scorpan absorbs the tree of harmony along with the energies of the princesses, and it's up to Fluttershy to save the day by sealing away Scorpan with the Chaos Mirror that Discord left her.
S07E03: Fluttershy in Chaos Land: When Discord decides to have Fluttershy over for tea, he summons her to his realm. Unfortunately, he forgot to tell her where his house was and she must maneuver through the tricks and traps of the Chaos Dimension.
S07E04: It's a Secret to Everypony: When Rainbow Dash finds out that the Wonderbolts are keeping secrets from her, she tries to find out what they are only to realize not all secrets are worth knowing. (Based somewhat, the original idea anyway, off the episode Homer the Great)
S07E05: Griffonstone, My Hearts Devotion: When Gilda invites Fluttershy over to Griffonstone to apologize for how she's treated her in Ponyville at the urging of Gabby and Rainbow Dash, Fluttershy is amazed to see just how much Griffonstone has changed since Rainbow and Pinkie's visit.
S07E06: It's Vanhoover, Eh?: Twilight Sparkle and Rarity are called to Vanhoover to meet up with an old acquaintance of Fluttershy's who it turns out was responsible for Fluttershy's shy behaviour in the first place.
S07E07: Grilled Cheese: Cheese Sandwich returns this time to throw a party for Fluttershy, but Pinkie is unsure of whether or not Cheese has an ulterior motive.
S07E08: The Flight of the Dash: Rainbow Dash injures her wing during practice, and ends up confined to her house just in time for tornado duty. It's up to Fluttershy to take the reins and coach her friend back into health.
Will post more later.
