[Twilight Sparkle opens a door at the bottom of the staircase with dark magic, revealing a negative vision of the future]
I don't know! I opened the door and-
Doesn't matter to me. You failed the test, Twilight!
[Twilight is horrified, commercial break]
I don't understand! The test-
Not only will you not move on to the next level of your studies, you won't continue your studies at all!
I... you didn't say anything about no longer being your student if I failed!
But... what do I do now?!
[She looks up and sees a stained glass window of Sombra's victory; she drops in sadness and cries.]
Spike
[voiceover] Twilight! Twilight?!
[In reality, Twilight is staring at the door hypnotized by Sombra's dark magic.]
Spike TWILIGHT! TWILIIIIIIIGHT!!!!!
[Twilight hears him and comes to her senses; he comes downstairs.]
Spike
[rapid fire] I know you told me to stay up there, but you were down here for such a long time and you weren't answering and I got worried, so I came down here, and you were just staring at that wall and... I was calling your name, but I couldn't seem to get your attention, and... What were you looking at? I mean, it's just a wall.
[The door's magic affects Spike]
Spike
Ponyville? Well, how did I get... No! I-I don't want to go! Please, Twilight! Don't make me!
[Twilight closes the door, snapping Spike out of it.]
King Sombra's dark magic. A doorway that leads to your worst fear.
Spike
We were home... you told me you didn't need me anymore. You were sending me away.
A fear that will never come to pass. I'm never gonna send you away. And I'm not gonna fail my test!
[She uses her own magic on the door, allowing them access through.]
I wish it had been me who ultimately made it so. But it wasn't.
Twilight, as I understand it, Spike brought Princess Cadance the Crystal Heart, because you weren't sure how quickly you could find a way to escape from the tower. You weren't willing to risk the future of the citizens of the Crystal Empire in an effort to guarantee your own. Far better that I have a student who understands the meaning of self-sacrifice, than one who only looks out for her own best interests.
[Celestia nods happily. Outside...]
Spike
She's totally gonna lose it! [breathes] Keep it together, Buddy. Gotta stay strong...for Twilight!
[Twilight throws the door open. After a pause...]
[The others cheer happily and Spike hugs Twilight.]
Spike
Maybe Applejack needs help realizing what she needs help with! Like, maybe her back itches!
Huuuuh, that does feel... good...
Spike
[laughs] See? Or you might need help remembering your favorite song! [singing] The Dragon is the finest creature ever, there's more to him than just guarding treasure!
I don't think that's her favorite-
Spike
Or you might need help breathing!
Breathing? I certainly do not-
[Spike inflates Applejack with a pair of bellows. Applejack then deflates, sending Spike into a bush.]
Spike
See? There are plenty of things I can help you with, and you don't even have to trouble yourself with thinking of them.
No I'll think of them. Let me think of them.
Spike
But I still don’t get why the Princess would be so late.
She’s bringing an important visitor. That could be part of it.
A visitor who is important and slow!
Maybe it’s somepony so terribly important, she still had many more terribly important things to do before she got here.
Spike
[tugging Twilight's tail] Maybe the visitor has a deer antler, a goat leg, a bat wing, and a snake tail!
[rolling her eyes] Yeah, right. That’s Discord.
Why in the wide wide world of Equestria would Princess Celestia bring along someone like that?
Spike
M-M-M-Maybe you should ask...her!
[Spike overhears Scootaloo in the Cutie Mark Crusaders' treehouse]
Has anyone seen Tank's head? Where's its head?!?
[Spike drops everything and runs in]
Spike
[angrily] What have you done to the turtle!?
[Scootaloo and Tank are covered in paint, Tank's head pops out of its shell]
Ohhhh, I totally forgot he could do that.
Spike
Fluttershy, where are you going?!
You seem to have everything under control.
Spike
Fluttershy, we need you! You have to power up!
I'm sorry, it's just that nothing is making me mad.
[A firefly buzzes by, Mane-iac whips it down]
Oh, goodness! Are you okay? [to the Mane-iac] Are you kidding me? I mean, I know you're evil and everything, but, you hurt a teensy, little, harmless firefly!? Really?! Well, you're just a great, big, meanie! [voice getting deeper] There! I said it! What makes you think you're so special?! Like the rules of common courtesy don't apply to you?! [metamorphoses into a gigantic, muscular pegasus] Why don't you pick on somepony your own [shouting] SIZE! [huge roar]
You've been wondering what you are meant to do as a princess. Do you know now?
As princess, I believe I have the power to spread the magic of friendship across Equestria. That is the role I am meant to have in our world! The role I choose to have! But I didn't defeat Tirek on my own, it took all of us to unlock the chest.
Then it is unlikely you are meant to take on this task alone. [opens door, showing thrones for the mane 6 and Spike]
M6Mane 6/Spike
[gasps] Wowwee! Wow...
You are now Twilight Sparkle, the Princess of Friendship.
[Rainbow Dash, Rarity and Spike test their thrones]
But what is the Princess of Friendship without her friends?
Spike
[muffled] A little help?
Spike
Of course! What can I do?
[door opens]
Spike
Whoa, what happened to you?
[groans, looking tired] Sorry, Spike. I just... [yawns] ...need a quick... nap. Napkin! Tell the delegates I'll... [trails off]
She's been awake for 3 straight days preparing for the summit. We need to make sure she gets some rest today. She'll never be able to attend the welcome reception in this condition. Can I count on you to see to it that she isn't disturbed?
Spike
I promise! I won't let you down!
Spike
[to Twilight and Rarity (in their rock disguise)] I don't want to be Dragon Lord or dragon toast, and I stopped glowing, so let's sneak out of here!
DTDragon Lord Torch
Where do you think you're going, little dragon?!
Spike
[nervously] Oh, uh, hi, Your Lordship. Uh, I was just going home!
DTDragon Lord Torch
You don't get to leave unless I say you can!
Dad, look at him. He's just a runt. Besides, he doesn't even wanna compete. Let him go.
DTDragon Lord Torch
[chuckling] He is rather tiny, heh-heh. I could squish him with my pinky claw.
Spike
[chuckles nervously]
DTDragon Lord Torch
That wasn't a joke, it was a fact. When I want you to laugh, I will say "Be amused!"
Hey, you, little fella! I've thought about it, and your plan makes sense. Let's do it.
Spike
Really? Great! It's a deal!
Just so you know, this doesn't mean we're gonna pick flowers or exchange necklaces or whatever pony friends do.
