Previously a fight started in Baltimare involving ponies against griffons.

Griffon bomber: blow up the cars!
other GB: *blows up car*
Sean: Damnit!
Shredder: At least MOST of us have a way to escape.
pelangi, rainbow Dash: Kill the griffons already! *kills griffons*
Pinkie Pie: *shoots grenade held sejak a GB*
Sean: Good work Pinkie.
Griffon 3416: *attacks pelangi, rainbow Dash, but gets her neck broken*
pelangi, rainbow Dash: That oughta teach anda not to mess with me!
Canterlot soldier: They're retreating!
Sean: A few of them are heading into that barn.

So the eight ponies, and hedgehog check inside the barn.

Twilight Sparkle: I don't see anything.
Applejack: It all seems clear.
Canterlot soldier: How can anda know for sure? Did anda even look?!
Applejack: Yes, and there is no one there
Canterlot Soldier: I think you're lying bitch, *kicks support beam causing the floor to fall*
hiding griffon: Don't kill me!
Pinkie Pie: hei that's Gustav.
Gustav: Don't kill me! I was here for the whole fight.
Canterlot Soldier: I told anda there was someone hiding anda dumb bitch!
Applejack: Will anda stop calling me a bitch?!
Sean: *steps between the two ponies* allright enough with the sexism. Now Gustav, why were anda hiding here?
Gustav: I didn't want to fight, but they made me come here. I figured if I stayed here then I wouldn't have to kill anyone.
Pinkie Pie: Gustav is nice even though I thought he ate Mmm.
Rarity: Oh not this again.
Pinkie Pie: Mmm is this cake I was going to enter into a desert competition until these three did it! *points at pelangi, rainbow dash, rarity, and fluttershy.*
pelangi, rainbow Dash: Don't remind us!
Pinkie Pie: Fine! But you'll miss out on the assumptions, and flashbacks!
Twilight Sparkle: We should probably get going.

After the stuff that happened in the bangsal the eight ponies, and hedgehog left with Gustav.
