I think we all recall Megan McCarthy saying that Flash will not be a character in Season 4. Either she lied...or the more logical explanation is...Hasbro forced her to make him appear (Thank you once again Hasbro for continuing to destroy MLP like you do with everything else you make).
But back to the subject...while Flash did appear, even if only briefly, this DOES NOT prove he is coming back. For all we know, he just appeared to make everyone say "OMG IT"S FLASH!!"
. I mean many background characters have appeared over and over...like Fancy Pants, yet he never makes anymore major appearances.
So...in truth, Flash has made a cameo appearance, but that DOES NOT mean he will return and become Twilight's official romance; That has yet to happen, so until it does, she is still single and he is not "back"
The MAIN reason I say all this is because of my own pairing of Twilight with my original character COURAGEOUS HEART.
I am NOT going to stop my writing just because of what happened in today's episode. My work will continue on for as long as possible...at least until I reach the end that I am planning, whether that happens when Twilight gets an official romance or not (Hoping NOT).
Over the past year since I started, my stories along with my own characters have become a big hit here on DA and elsewhere.
1. I have many friends and watchers here that love my stories and wish for more. They also love how Courageous was introduced and how he slowly became who he is, as well as got together with Twilight (Not to mention it all happened BEFORE Flash was ever named or made) 
2. I have heard from a friend that he saw a discussion on Tumblir once with the subject on Courageous Heart. Everyone there was saying how much better he is compared to Flash. All that gave me a major boost. 
3. My popularity has grown high in only a year. For most writers on DA, that is rare and hard to get. This proves my work is good; Good enough for Hasbro to notice...if they ever did 
4. While he may look like an alicorn, Courageous Heart is NOT a true one (If he cant use magic, then he is a false alicorn). His features and backstory are what make this pony that good. Some don't see that and are too dumb to even bother reading. 
So, in short, no matter what happens (Even if Flash appears again and talks...or more.) I am NOT going to stop writing, nor stop with Twilight paired with Courageous.
Or as they are now called: "TWIRAGEOUS" (you have to admit it is better than "Flashlight"
. The Pairing name, not the whole pairing itself.)
Also, let us not forget that around half of the Brony Fandom like Flash, so we will have to see if Hasbro will go all the way or not.
That is all I wanted to say. So yeah 
TWIRAGEOUS FOREVER!!!!
