At the camp/Mac's backstory

This is how we come to the camp and Mac's backstory goes in Thomas and Twilight Sparkle meet the Hobbit: An Unexpected Journey.

[At night, we see Bilbo walking to Myrtle, his pony]

Bilbo: Hello. Who's a good girl? [thinks about the others then gives her an apple] This is our little secret, Myrtle. You must tell no one. [shuses]

[Then screams are heard]

Twilight: [wakes up] What in the world was that?!

Kili: Orcs.

Thomas: Cinders and ashes! Orcs?!

[Thorin wakes up]

Fili: Throat-cutters. There'll be dozens of them out there.

Kili: They strike while everyone's asleep. Quickly and quietly. No screams. Just lots of blood.

Michelangelo: And Astronema had an Orc as a pet. [laughs]

Thorin: You think that's funny?

[Everyone looks at Thorin]

Thorin: You think a night raid by Orcs is joke?

Elgar: Look, we never meant anything by it.

Thorin: No, you didn't. You know nothing of the world.

Balin: Don't mind him, laddies and lassies. Thorin has more cause than most to hate Orcs.

Mac Grimborn: You don't understand. Not all Orcs are evil. After Sauron corrupted Smaug, I helped King Thror to try and reclaim the ancient Dwarf Kingdom of Moria.

[Then we see Orcs and Dwarves battling in Moria]

Mac Grimborn: [narrating] But the enemy got there first.

[Then Mac battles Orcs]

Mac Grimborn: [narrating] That was then I learned that Sauron was using another as a pawn to his selfish ends: Azog, my brother.

[Then he sees Azog battling Thror]

Mac Grimborn: The Lord of Mordor made him swear to wipe out Durin's line.

Twilight: Where did he begin?

Balin: By beheading the king.

[Azog roars as he beheads Thror as Mac and Thorin watch]

Thorin: **NO!!!!!!!!!!!!!!!!!!!**

Mac Grimborn: Then Thorin's father, Thrain, was driven mad by grief. He went M.I.A. "Missing in action." But then I had no choice...

[Then Mac confronts his brother]

Mac Grimborn: [narrating] But to face down the Orc Goblin.

[Then they fight]

Mac Grimborn: Azog, no!

Thomas: [narrating] Brother versus brother.

[They continue fighting until Mac cuts off Azog's hand]

Azog: [screams]

Applejack: So, Azog, the Orc Goblin, your brother, learned that Durin's line wasn't so easily broken?

Mac Grimborn: Yes.

[Then Azog and the Orcs retreat as Mac and the Dwarves charge them]

Mac Grimborn: [narrating] We rallied and drove the Orcs back! And the enemy... Was defeated.

Balin: But there was no feast, nor song that night, for our dead were beyond the count of grief.

Mac Grimborn: [narrating] We few survived. And Balin thought to himself, that there's one he could follow and one... He could call King Under the Mountain.

[Thorin turns back to Bilbo, Gandalf, his kin, and our heroes]

Mac Grimborn: But there was something I shouldn't have done.

Rey: What happened?

Gordon: Mac, what happened to Azog?

Thorin: He slunk back to the hole whence he came. That filth died of his wounds long ago.

Mac Grimborn: That *"filth"*was my brother. I failed him. Because I was Mac Grimborn. Son of Theoden. Nephew of Ecliptor. Heir apparent of Celebrimbor. Brother of Azog the Defiler. Uncle of Bolg. A legend.

Rey: Middle-Earth might need that legend. We might need your help to conquer the dragon.

Mac Grimborn: Rey, I failed Sauron, Azog, Smaug, and Bolg.

Rey: [stands up] You didn't fail Sauron. Sauron failed you. We won't.

[They don't realize that our villains and Orcs are watching them]

Cozy Glow: Send word to Lord Azog, Starscream, that we found the heroes and the Dwarves.

Starscream: As you wish, Supreme Leader. [he does so]
