Castles. (Spoilers)

It's been awhile since I watched "Princess Twilight Sparkle" part 1 and 2. I had a random thought in my head, though, and I didn't know what else to do with it.

I was uneasy about Twilight's library getting torched. Ok, a little more than uneasy; I was pissed off. I loved the library, and I thought that Twilight getting a castle was unnecessary. However, there's obviously going to be things coming after the Elements of Harmony. Ponyville needs a castle. I don't know if they're going to do the whole "put walls around Ponyville and put everyone in town in the castle when stuff starts attacking" thing, but I hope they do.

I have a strong feeling that Twilight's home will continue to be the Town library as well, or at least I hope.
