I’ll say, given that I had no real problem with Flash save from being a random love interest, that this was a completely benign reappearance. I’ll joke he was bedroom-eyeing Twi there, but in the larger picture, he’s Cadance’s lead guard, he didn’t talk, end of appearance. That’s a nice nod without pandering or forcing.

That kind of makes EQG’s friendship plot completely contrived doesn’t it?

YES. YES. This.

That’s not what I meant; he was worthless in the movie, at least in my opinion, because he is bland and uninteresting. Giving him a cameo in the show is bad for the sole reason of him simply being there in the show, when he should only appear in Equestria Girls; saying EQG is non canon will also be more difficult now.
 
 
@Background Pony #5888  
People like you are one of the primary reasons why this is a bad thing. The ‘waifu thief’ meme is the most annoying, cancerous thing I’ve ever experienced in a fandom.

Yeah, if Grumpy Cat, Slender and now Flash is any indication Friendship is Magic is hardly “Meghan’s show”.

Maybe they could put Derpy and Flash in the same scene just to screw with the minds of the Bronies.
Background Pony #A74E
I can’t help but get a chuckle out of some of these reactions to Flash. You guys wanted Derpy back, but apparently it came with a minor cost.
 
The truth, however, is that Pony Flash Sentry is a completely different individual than Brad. So lighten up.

You know it was never said that both flash sentrys would never appear in season four so it wasn’t exactly a lie

As opposed to other background ponies that are merely worthless and in there for no reason?

I kinda hope Flash shows up again and acts like he does in the comics.

But that was in a different dimension ,surely this innocent non-human pony sentry will not incite our your probably overrated rage will he?
Background Pony #C937
I think it’d be great if he just made non-speaking cameos looking smug. Rub it in.

Only with how it pertains to the story and main details, she can’t be held accountable for everything.
Background Pony #81B3
Hey, maybe we should send Hasbro angry letters complaining about Flash begin offensive toward disabled people and see if it works. XD
Background Pony #2D77
@D50  
Because he’s worthless and is likely only in the show because of Hasbro demanding a dreamy boyfriend for Twilight?
