I really love the fact that they gave the Cerberus from the time traveling episode a mention in the finale. In THAT episode Mr. Devil got released from his prison. That's kinda genius.

You can see Twilight got very mad when he destroyed her tree-house. That was basically the thing that unlocked her Super Saiyan powers haha. I guess it's ok now though, she gets to live in the tree of harmony-castle-thing.

I think I vaguely remember that...? I kinda remember the Cerberus from before... could you remind me which episode that was?

I don't really remember the name, but it's the one where twilight from the future visits twilight and then she goes crazy trying to prevent whatever happened to her future self. One of the things that happen is that a Cerberus "attacks" the town. Turns out that same Cerberus was the one and only that was supposed to be watching over this villain.

Those feels when I look at that picture of the tree... I figured she would have to move out eventually, but they had to just blow it up. Awesome scene as a whole, but sad at the same time. I'll miss that Library...

I was ecstatic when I saw Tirek in this episode. As someone who watched the G1 MLP 'Rescue from Midnight Castle' film, I always thought his character would be a perfect fit, and they do it well here, even giving Equestria's own version of history on the matter. Only thing I'm disappointed with was we didn't get to see Scorpan besides the history lesson itself, but small gripe. Discord's inclusion was also very fitting, and as always, he tends to steal the scenes he's in. I also liked the fact that he was the one to learn a lesson through Twilight, and bestow an object. It kinda comes full circle for him since his reformation, and we get a real sense that he has changed for the better. Though, hopefully he'll still be a bit of a trickster in later season/s. Also full on super fight scene, though it took the destruction of the place Twilight settled into Ponyville, the Iconic Golden Oaks Library. So many important memories from the show were made there, that it's such a shame to see it get engulfed in a burst of flames. I hope they can somehow rectify it later down the line. And with continuity throw backs as far as season 2, you have a bang up episode. Congrats DHX on another ballpark homerun.

My opinion on the finale as it was the first finale I've watched from the show and it was so awsome! Since I joined late s4 I didn't quite get where all the keys were from (I didn't know where rarity and pinkie pie's where from) but I didn't feel like I missed too much. I also couldn't help thinking about "IMMA FIRING MA LAZER" when Twilight fired his epic laser of doom on Tirek And the ponies "mega evolution" were also very well done and so awsome Unfortunately twilight's house had to go away but to make THE BEST fight I've watched in a loooooong while! so IMO it was worth it

I think that Discord planned everything ahead. He knew what was in the box, what the keys were and knew how dangerous Tirek was. It's also rather odd how to only window he mess with is the one decipting Twilight Sparkle. I think he must've figured that to obtain the last key and thus defeating Tirek he was to let Twilight give up her magic and prove her friendship. He also knew Twilight wanted a kingdom to rule, and she got that in the end! It would also be a test to see if Twilight actually cared about him even after he betrayed them and he lost his magic.

I don't know. He may have known "the power" that was within the box (but not necessarily the use) and how to open it, but I don't think there was an actual plan with regard to Tirek. If this was his plan all along, then that would mean that he was pretending to betray the ponies and take Tirek's side. He may cause mischief with most, but he certainly had stopped any and all deceiving with Fluttershy, who he regrets betraying the most. If Discord knew the amulet from Tirek was the key for Twilight, then I doubt he'd have left the window pane of Twilight as it was for Tirek to notice, because at that time of getting the amulet, Discord could go off to the main 6 and get the box opened. No, I think Discord set out to do as he was called, to bring Tirek in (since he was the one who could find him), but he didn't expect Tirek's influential words to relight the flame of his own ways by having his current situation described as just another prison .

As others have said, it was epic. Of course most of the epicness came from the 2nd part, especially the fight between Tirek and Twilight. I'm so glad they put thought into this finale, especially when bringing back an old foe. I mean, this finale could be considered dark compared to other episodes this whole generation, yet it worked so well. The first season didn't really have a finale, and honestly, the 3rd season's finale was too song-filled. Season 2's finale was at least decent, but how it ended pales in comparison to this finale. Of course you've got Discord, the franchise's goofball, up to his old tricks with the mane 6. I saw one image before watching this finale, and it was Tirek absorbing his magic. Because of that, I thought he was going to be one of the first to go, but it turned out that not only was he not, but he also helped Tirek to do so with all the other ponies. I guess the sudden reversal though between the two of them was kinda expected after seeing how more powerful Tirek became. All in all, it was a great finale, but not so great as we have to wait until next year for Season 5. I do have a troubling question though. Did Discord lose his magic forever? From the point when Tirek absorbed his magic and onward, he had used no magic at all, even after every other pony was restored. In much the same way as people were unsure about Twilight becoming an Alicorn, I am unsure about a magic-less, and possibly non-mischievous, Discord. By taking the discord out of Discord, he becomes a simple bystander. That does not sit well with me, especially since he's my favorite character of the franchise (Discord is best pony). I just hope that this isn't the case.

Now I'm reminded about the final battle in Yoshi's Island.
