I got 'tagged' or something. While I ain't gonna humour the notion in its entirety by annoying a further eleven people and forcing them to answer some questions, I'll answer the ones that were sent to me.
1. Who is (the) best pony?
Rarity, and Celestia.
Personally, Rarity solidified herself as my favourite in S1E19; A Dog And Pony Show, and that's just been continued ever since. I like her because, of the Mane Six, she's... Pretty much the biggest hypocrite, but somehow remains true to her spirit of generosity despite it all. Tabitha St Germain's voicework on her is also excellent, and Rarity's lines and reactions crack me up more often than the others. She's also a complete karma Houdini and very fun to write for.
However, I also adore Princess Celestia. Like everyone I've got my own notions of what she's really like, can can argue based on the show. She is by far my favourite character to write anything for, because I picture her as the adult that's forced to be mother to thousands of children who all look up to her and expect her to act in a particular way... And at times she gets sick of it, and longs for a break.
My favourite line from Celestia definitely comes from S2E20; It's About Time: "Good morning, Twilight! Love the hairstyle! Well, Happy Tuesday!" /walks off. /no explanation given.
3. How does magic work?
My personal theory is that, in universe, magic is powered by the bonds between ponies, as a collective effort. There's a magic 'field' that pervades and surrounds everything in Equestria, that ponies can tap into either indirectly (as Earth Ponies or Pegasi) or directly (as Unicorns and Alicorns). The more friends (proper friends) a pony has, the more powerful they are, when tempered with trained talent and skill. Magic powered by a bond of true love between two ponies (as demonstrated with Cadence and Shining Armour) is on a similar level of power to the Elements of Harmony, which requires a minimum of two ponies and some tricky genetics and fate.
As for mechanics? It's been shown to act somewhere between pure force and some kind of energy, but I don't think it's worth analyzing to that degree. We also know that some creatures have innate magical ability (Cockatrice, CHangeling) and others certainly aren't powered by friendship (Windigo, Discord). In fact it could be argued that both friendship and hatred work as sources of power, although ponies as a race can only use the former.
4. Do you think Chrysalis was truly evil?
"Evil" is relative. As I wrote shortly after the episode in this short story, I don't think a Changeling needs to dominate to exist, but I think Chrysalis was portrayed as something more like a concerned 'mother' who was willing to go to serious extremes to provide for her 'children'. Unfortunately for her, so's Celestia.
5. What about Discord?
Discord is Chaos, let's not confuse that with Evil. By the same Token, Celestia and Luna (as one unit) represent Order, but I'm sure that in their thousands of years of life, they've committed acts that would not be considered 'good'. I think both of them need to exist, or else the universe in which Equestria exists would ultimately stop working. Unfortunately, the two are constantly at odds with one another, although perhaps in time they could form a mutually beneficial partnership.
Of course, having said that, Discord does delight in the apparent torture of beings under his rule, and is completely egotistical and concerned with only his own satisfaction and amusement. In that way, yes, he's 'evil'.
6. What is your favorite meme?
Hrm. I dunno. I tend to smirk at most of them. Like any joke, delivery and timing is everything.
7. Favorite episode?
Hrm... Possibly S1E20; Green Isn't Your Colour. I love the play-off between Fluttershy, Rarity and Twilight in that episode. As mentioned above, I also enjoy A Dog And Pony Show for Rarity's magnificent hamminess, and I've had favourite moments all throughout season two. Of course, there's also Party Of One. Who doesn't like schizophrenia and possible mental breakdowns on a kid's show?
8. If you found yourself in Equestria, what species would you want to be?
In all honesty? Probably a unicorn so that I could retain the semblance of having hands. But if I'd been born a pony, Earth Ponies are pretty cool.
9. If you could, what pony would you date?
Yes, well, next question!
10. Would you adopt the filly version of Queen Chysalis?
After screaming for several hours at the concept of a talking, shapeshifting, half-dragonfly, half-horse monstrosity on my doorstep, possibly.
11. WHO'S IDEA WAS THIS TAGGING CRAP?!
No idea. I ain't continuin' it.
Right, right, update news, I suppose. I've finished my exams (rejoice!) so I'll get back to writing pony soon enough. Mainly scrambling around to find my inspiration again.
