Spike: Raaaarityyyy

Claire: Auntie, is daddy okay?

Twilight: Oh, he’s fine. He’s just worried about your mom.

Claire: Why? Isn’t she just having a baby?

Twilight: Mmhm. But having a foal can be very painful for a mare, so your dad wants to be in there to comfort her

Claire: Why doesn’t he just go in then?

Twilight: Weeeelllll, last time we were here when you were being born, he was kicked out because he was being a little too….overprotective.

Claire: Like how?

Twilight: Oh you know how he can get. I’ll leave that to your imagination ;)

Crystal Clarity: “¿Tía? ¿Papá era así cuando nací?
Twilight Sparkle: “Sí, pero lo está haciendo mejor”.
Crystal: “¿Qué paso con el tío Flash cuando tuviste a Starburst?”
Twilight: “Bueno… aún así, Spike está mejor”.

Spike: Raaaarityyyy

Claire: Tía, ¿papá está bien?

Twilight: Oh, está bien. Solo está preocupado por tu mamá.

Claire: ¿Por qué? ¿No es solo que va a tener un bebé?

Twilight: Mmhm. Pero tener un potro puede ser muy doloroso para una yegua, así que tu papá quiere estar allí para consolarla.

Twilight: ¿Por qué no entra entonces?

Twilight: PueeeeSSSSS, la última vez que estuvimos aquí cuando tú nacías, lo echaron porque estaba siendo un poco demasiado… sobreprotector.

Claire: ¿Cómo fue?

Twilight: Oh, ya sabes cómo puede conseguirlo. Lo dejo a tu imaginación https://derpibooru.org/images/496638

Crystal Clarity: “Auntie? Was daddy like this when I was born?”  
Twilight Sparkle: “Yeah, but he’s doing better.”  
Crystal: “What about Uncle Flash when you had Starburst?”  
Twilight: “Well… still, Spike’s doing better.”

The look on Spike’s face makes this pic for me!

Maybe a grown dragon is just in the way?

Implications.

@HighRollerHydra  
Are you sure they weren’t referring to Spike?

@Background Pony #1607  
More trolls that hate change. Ignore ’em and let them starve.

@Background Pony #C1AE  
Did… Did you just attempt to stir up Twilicorn bullshit… ON A FREAKIN SPARITY PIC?!

He looks so silly compared to the anguish he’s facing.

His face is frikkin’ priceless. XD

@Background Pony #C1AE  
Well, she IS a princess now.

No wings.

That face.

Lol, his face is so perfect.

Twilight laughs at your misery.

Going by the description, he got kicked out last time for being a bit too “overprotective.”

Kinda an old-fashioned hospital if it doesn’t allow fathers in to watch the birth of their children.

Crystal: “What’s going on in there?”
 
Twilight: “Well… you see.. uh…”
 
Crystal: “…?”
 
Twilight: “Bah! This isn’t even my responsibility! Spike, quit crying and get over here and tell your daughter about the birds and the bees!”
