Luna will become frustrated at her lack of air time during the previous two seasons and revert back to Nightmare Moon, forming an alliance with Queen Chrysalis to bring about the never-ending night. Meanwhile, Discord is just sitting back and watching all of the chaos he has orchestrated, however all 3 villains are eventually vanquished by the concentrated power of love between every citizen in Equestria, which amplifies the power of the Elements of Harmony exponentially. Or, it could just be a two-part episode featuring the life and thoughts of Diamond Tiara. Who knows?

What are you talking about? Discord has already met Hexadecimal in the show:

I'm a 25 year old little kid, does that count?

Considering that the show is an international phenomenon that has been or is being aired in 20 different languages in some 140 territories around the world, you can imagine just how many bronies there are out there. But, let's look at the stats for the center of the brony community, at least in the United States and other English-speaking countries, which can best represent the brony phenomenon domestically: Equestria Daily. (You can see the stats and Alexa rating here.) In the United States, it ranks #7544. By comparison, square-enix.com ranks in the US at #5980; Funimation.com has a US rank 7,451; and americanidol.com ranks #9610 in the United States. Now, Alexa ranking only give an approximation of how big a fanbase is by how many people go onto these websites, but you can see that My Little Pony: Friendship is Magic is about as popular in the United States as Square-Enix, Funimation, and American Idol from these examples. There is also the fact that Equestria Daily has garnered over 200 million page hits in a year and a half of existence, and averages around 250,000 hits per day. That says quite a lot, especially considering EqD covers nothing other than MLP:FiM related topics. BronyCon has reported about 4000 attendees over the past weekend in New Jersey. AnimeNEXT, which also takes place in New Jersey, had about 8000 in attendance. We all know how popular anime is in the United States, and just how broad a category anime is, so it is astonishing that a convention covering MLP:FiM specifically drew half the attendance of a large summer anime convention. I would estimate that bronies number in the millions in North America, and the 10s of millions worldwide. The statistics speak volumes.

What you saw in Ponyville is only a few of the books that Twilight took charge of when moving to Ponyville. She often teleports back and forth between Ponyville and Canterlot to retrieve books from her real personal collection, as shown below.

I think she has a home in Cloudsdale, but she fell out of it and landed in Ponyville. Her parents are looking for her, but she can't fly high enough to reach Cloudsdale and she is too ashamed to admit that she fell out of her own home.

I would say start with the first episode. It ends on a cliffhanger, so if your friend is interested he will want to watch the second episode, too. If he doesn't show interest after the first episode, well then you planted a seed and maybe if you leave it alone it will grow. If you don't want to start with the first episode, then I would go with an episode that showcases some of the humor and awesomeness that the show has to offer. For most people that I know that would be Sonic Rainboom. Other good suggestions would be Dragonshy, Bridle Gossip, or Mmmystery on the Friendship Express. If they are a Disney fan they will probably be sold on Winter Wrap Up. Just remember, not everyone is going to like the show, or even give the show a try. I work with a few people that think it is childish to watch cartoons at all -- those people are out there.

You would probably experience a temporary distortion of reality, except ponified.

Once a doll is enchanted, it stays enchanted forEVER!!!!!

When I first started watching the show, I would have said Rainbow Dash without hesitation. Twilight Sparkle has really grown on me, though.

Given what we do know about various locales, I would infer that the part of Equestria that contains Ponyville, Canterlot, and Cloudsdale are in an area of land similar to the Central Valley in California. I have come to this conclusion based on the contrast of other nearby locales such as Dodge Junction from "The Last Roundup" and Appleloosa from "Over a Barrel". Ponyville appears to be situated in a lush, fertile valley with various streams and estuaries making it an ideal place for the earth ponies to work the land, as the Apple family does in Sweet Apple Acres. We know that there is a mountain range in the distance, upon which Canterlot is located. Dodge Junction is supposed to be the first stop after Canterlot, as mentioned in "The Last Roundup", and the scenery there is straight out of the wild west with geography similar to what you may find in the Great Basin, which is coincidentally situated east of the Sierra Nevada mountain range. We can only assume that Appleloosa is in the same direction. Also, in "Dragon Quest", Spike and friends journey through woods and over mountains to reach a volcano crater that is home to the dragons. This is very similar to the geography in the Sierra Nevada mountain range, which does indeed have a few active volcanoes in it. Based on this, I would say that there is likely a bay that reaches into Ponyville Valley similar to San Francisco Bay, and it would be somewhere west of Ponyville. The only thing that throws me off are the names of the cities that are apparently nearby, which follow after names of East Coast cities. We know from "The Cutie Mark Chronicles" that a rainbow over Ponyville can be clearly seen from Manehattan, and one would be lead to believe that Fillydelphia is nearby since it mentioned twice in the show. That is just my conjecture, anyways. It is a world of magic, though, so anything is possible. A picture of California, so you can visualize it (from Wikipedia):

Yup, found it:

I think Applebloom is Blossom, Scootaloo is Buttercup, and Sweetie Belle is Bubbles, actually.
