AJ: Lookie here, Rainbow Crash. Ah was Andy’s favorite toy first, and no one is gonna take him away from me.  
Dash: What the heck are talkin’ ‘bout? Where’s that bonding strip?  
AJ: And another thing: stop it with this spacepony thing! It’s gettin’ on mah nerves!  
Dash: You sayin’ you wanna lodge a complaint with Wonderbolt command?  
AJ: Oh-ho, so you wanna do it the hard way, huh?  
Dash: Don’t even think about it, cow-girl.  
AJ: Oh, yeah, tough pony?! (pushes Dash, her helmet comes off)  
Dash: GASP (starts choking for a few seconds, then sniffs the air) The air’s…isn’t toxic? How dare you try to knock off a spacepony’s helmet on an uncharted planet?! My eyes coulda gotten sucked outta their sockets! (puts her helmet back on)  
AJ: You actually think yer the Rainbow Dash? Oh, all this time, ah thought it was an act! Hey, everypony, it’s the real Rainbow Dash!  
Dash: You’re mockin’ me, Aren’t you?  
AJ: Oh, no no no no…DASH, LOOK AN ALIEN!  
Dash: WHERE?!  
AJ: LOLOLOL!

@Shritistrang

Rainbow Dash: “You’re mocking me, aren’t you? AJ?”  
Applejack: “No, no, no, DASHIE!! LOOK AN ALIEN!!!”  
Rainbow Dash: “WHERE?!!”  
Applejack: “(Laughing)”

Or underwater. Either one is fine.

Dash Lightyear: “You are one sad, strange little mare. I pity you.”

“BWAHAHAHAHAHAHAHA!!”

@TheOtherPinkiePie  
More likely, “Rainbow look a shadowbolt.”
