After escaping a near death situation Rainbow Dash was taking a nap in a cloud when she heard some ponies talking.

Stallion 43: I found her!
Rainbow Dash: Oh shit
Stallion 35: Get back here Fluttershy!
Fluttershy: I don't want you to kill me.
Stallion 43: Well I'm sorry.
Fluttershy: Someone help!
Stallion 43: *hits Fluttershy* Shut up!
Rainbow Dash: I'll help you.

Dash followed the ponies toward a slaughterhouse which was where the stallions were going to kill Fluttershy.

Fluttershy: Oh my.
Stallion 35: Nice isn't it? Don't worry we'll have one of these nice new machines rip you in half.
Rainbow Dash: Not on my watch. *hides*
Stallion 62: Easy with the box!
Stallion 89: Why don't you carry it if you're worried about the weapons?
Rainbow Dash: Now to save Fluttershy.
Fluttershy: Why do you want to kill all mares?
Stallion 43: Because we can.
Stallion 35: There's more of you then there are of us. We wanna change that.
Rainbow Dash: Fluttershy? Get over here.
Fluttershy: *walks*
Stallion 35: Where are you going?! *breaks Fluttershy's neck*
Rainbow Dash: D:
Stallion 43: Cremate her.
Stallion 35: Yes sir.

With one of her friends dead Rainbow Dash decided to leave the slaughter house.

Rainbow Dash: *opens door*
Stallion 71: I found Rainbow Dash!
Rainbow Dash: But you won't catch me *flies away*
Stallion 71: *chases Rainbow Dash* Come on, I'm not gonna hurt ya.
Rainbow Dash: Then what's with the gun?
Stallion 71: so i can Shoot your head off *shoots gun*
Stallion 62: You almost caused an explosion!!
Stallion 71: Yeah well I'm chasing someone here.
Rainbow Dash: *goes right*
Stallion 71: Oh- *hits barrels*

The explosion not only killed several stallions, but made it easier for Rainbow Dash to escape. Next time however will not be so easy.
