Issue 55, it showed a flashback of Dash in the Junior Speedsters camp, and Bow was shown to look like Blaze.  

@Deserter  
Which comic said that?

“What the fuck is an ‘anatomy’?” - Whoever animated this episode.

What’s up with Rainbow Dash’s body in this pic?

Ha! Brilliant XD

Noted

“Every Hearth’s Warming Eve, before I had to save the entire planet every weekend, I’d sit down on the porch and kick thunderclouds into the night sky, hoping to hit Celestia.”  
“Well, you obviously didn’t hit her.”  
“Actually, I thought I did once, but it was my brother, Blaze, wearing a Celestia costume. The only thing left was the fake horn… What I’m saying is, It’s Hearth’s Warming eve, and something needs to be electrocuted, so I’m feeling a little nostalgic.”  
“…I have a half-brother?”  
“You had a half-brother.”
 
Also, if IDW is to be believed, that’s Bow a couple of years back, but it’s IDW, so y’know, take it with a grain of salt.
