This story is a sequel to Too Late
Believing an interdimensional relationship could only go so far, the human Flash Sentry reluctantly turned down Princess Twilight Sparkle's offer to go on a date. However, after an initial heartbreak period, Twilight decided to ask out Flash's pony counterpart. Without the difficulties of an interdimensional relationship to scare him off, surely this Flash would jump at the chance to hook up with Twilight, right?
Well, let's just say Princess Cadance had sunk the ship a few months prior. The Princess of Friendship did not take learning this well.
This may or may not end with a funeral.
Enough is explained in this story to not require reading "Too Late" to understand what's going on. This story does mention only the most relevant parts of "Too Late", so it is recommended to check out "Too Late" if you want to learn more about what happened when, and immediately after, Twilight tried to ask out the human Flash Sentry.
Bahahahahahahahaha!
This story was hilarious and Twilight was funny in a satire way. I almost thought this story would end on a touching note but I should have remembered who was writing this. LOL.
Supoib!
Rarity of Fluttershy should be your only love, Twilight.
Shining ever had dignity to begin with?

Glad you liked it! Occasionally my comedy stories end on a touching note, but more often than not, they end on a silly one

With the Twilight x Rarity stories on the site, I'm not surprised she's not brought up, but I didn't expect to see Fluttershy mentioned as a possible love for Twi.

In canon, more than he sometimes gets credit from the fandom IMO.

Still slaying me with laughter!
Have another like!

And monochromatic was even who I was thinking about when I brought up Twilight x Rarity earler.
Dang. They even held a funeral.
SIMPSONS DID IT
You know, this story and its prequel got me thinking- has there been a story that makes a serious attempt to ship Princess Twilight with human Flash Sentry and deal with all the multi-dimensional logistics? The ones I can think of either break things off early because they know it won't work, are short stories that don't try to address those issues, or else are non-serious crack fics.

Off the top of my head, I don't know of any stories. But thinking about it, Princess Twilight and human Flash Sentry holding a relationship, in their case, really wouldn't be that hard even from a multi-dimensional standpoint, or at least I could make it work if I ever write a serious story where they got together.
Since pony Twilight's portal connects her castle with the school, her and Flash being together, from a distance standpoint, would be akin to someone in the US having a relationship with someone from Japan...if they could warp in seconds from their house to the city where their partner lives and vice versa. A downside would be that they can't communicate when Twilight's in Equestria and Flash is in the human world unless Flash borrowed Sunset's journal sometimes or she acts as their middlewoman of sorts -- no Interdimensional phones and all. But if Twilight could create another pair of journals for her and Flash like the one she has with Sunset, then their living in different worlds pretty much becomes a non-factor. All they would really need is for Flash to have a car to freely go to CHS's portal anytime he wanted to pick and later drop off Twi, which he does, and they might as well have lived in the same city at that point.
From what I can tell, things could become tougher once Flash graduates and possibly go to a college away from whatever the city CHS is. so he wouldn't be near CHS's portal anymore. But even at that point, a relationship between pony Twi and Flash could still be comparable to how real-life long-distance relationships work as long as they had journals or some other way to talk to each other with. If they didn't, then they could hit a brick wall without one of them moving to the other's world.
But for the Immediate timeframe, the only things I can see being a deal-breaker are if either Princess Twilight's and human Flash's personalities just weren't compatible to be a couple or if the former became too busy with her princess duties to hold an inter-dimensional relationship even with the ways around it.

Yeah, that's about what I was thinking. Depending on the rules of the mirror and the journal, dating wouldn't be too big a problem, but eventually one of them has to commit to live in the other's world at least most of the time and that's not going to be the princess. If Flash can't see himself ever doing that, then perhaps it is best they just cut it off now.
Still would be curious to see a story that seriously tries to tackle this. Ironically this is one pairing that doesn't seem to get as much attention from the fandom (unlike vurtually every other permutation of the main characters), at least as far as I've seen.
