Yeah, I missed the treehouse too. Feels.

@Beau Skunky  
And there’s this little kids show that was made into a movie. The movie includes missles, guns, violence, horrifying scences, and near murder parts. Like seriously. That movie is for kids five and under.

@Beau Skunky  
I know.

@Flutterpest  
Dude, if a tree blowing up is “violent,” you’d be surprised what other cartoons have done.
 
Let’s not forget Leonardo beheading the Shredder.

Isn’t this episode a little too violent for little kids? And for some reason I like seeing this library get burned. But I feel sorry for Twilight.

…yes.

The book may be kinda hard to damage in itself considering in season 2 it put up with being the focal point of a fight over it.

@someguy111  
Words of greatest truth.

So does anyone else realize that the Book of Harmony is probably gone too? Since Twilight was shown to keep it in the library.

“Noooooo! That’s where I kept all my stuff!”

Which is sadder?…

While the “castle” is supposed to be an upgrade it feels more like a cold, hard and hollow industrial complex instead of the tree which was a nice, warm, comfy, cozy retreat; like a little cottage in the woods vs. a factory.

Spring of 2013 called. They want their fandom mindset back. The writers gave us today’s episode, as well as a fantastic season.
 
Season 3 ended with Twilight getting her wings; Season 4 started with her trying to get used to them.
 
Just watch. Season 5 will start with Twilight searching the ruins of the old library to see if anything survived. That or it will start with her struggling to get used to the new castle, and talk about how the old library was so much simpler. Or some other thing to the same effect.

@Pony Paradox  
To be fair, Twilight herself & her owl looked pretty upset about it. She was so upset in fact, she started taking on Tirek herself. That sad look she gave just before fighting him was especially heart-rending.

Oh, man. That one book that’s on fire…

This… honestly devastated me. Hell, I’m still devastated. The Golden Oaks Library was probably the most iconic landmark in the entire show. Seeing it obliterated, without the characters even commenting on it, hurt even more.
 
But… I accept it for what it is - an unexpected representation of loss in an otherwise candy-flavoured cartoon, and one that really hit hard.

(Picks one up.) “Garfield Takes the Cake?”

@toonbat  
(drops a bunch of books)  
Oh really?

At least all the books that were lent out to the ponivillians at the time survived.
 
Oh, right. Nopony ever checked out a book from the library.

Avenge Golden Oaks!

What a loss this is.
 
Forever a place our hearts shall be.

The treebrary was where Derpy was first spotted and became the character we all know today. So many episodes used this place as a significant setting.
 
I…I need a moment…something’s in my eye.

@Beau Skunky  
It looks cold, it’s spiky and nowhere near as lively as the library, so this hole gets a clear F from me.

@Celestia’s Servant  
I know, that’s what made the destruction of the library tree so emotional in the ep’. The heroes needed to suffer some kinda loss, and losing the library is the closest thing to a character death they could probably get away with. It shows how far Tirek would go, and it gave Twilight that extra push to fight against him.
 
@toonbat  
I don’t think the castle is that bad honestly.
