Sky is. It says so at the top of the pic.

What to call this meme? “Vapor Trail spills the beans”? :D

@thps48  
This is not the interaction on the show, so the surrounding frames of the show don’t apply.

“…You know, maybe we should consider more solo training now that we’re better.”
 
“Huh? Why would you say tha-”
 
“I think we should see other ponies.” quickly flies off

@Fwelin  
Unless you had seen the frames immediately before these ones.

@thps48  
Usually they at least SHOW the father in the reaction shots, though…
 
Plus, she says your foal, and then it immediately cuts to those two, like she were talking to them.

@Fwelin  
Yes, only the father shows any emotion upon hearing he’s going to be a father in movies and television. :T

Given who were shown reacting first, Twi and Dash are the fathers?

Don’t forget the basic rule in story telling: “show, don’t tell”  
Don’t tell us you’re pregnant, but show us you getting impregnated

Welp, time to hit the old dusty trail.  
“What about my mom?”

Good.

Yeah! Jerry! Jerry! Jerry! Jerry!

Dammit, I love this.

“Way to drop the bomb, Trail…”
