Well I did this in a free hour, and for those who have followed Midnight’s story, you will know that Flash is there sent by Shining Armor and Candace, but above all because he was already part of Twilight’s guard. And they have a relationship that is difficult to keep even a little secret.
That’s not to say that they don’t have their moments like Flash talking to her in the map of harmony room, or when they learned to dance together, Twilight wasn’t a great dancer and Flash had never had time to learn, but they did it together and They like me.
The girls know about their relationship so they can act freely in front of them and Twilight likes to snuggle into their necks and well who is he to refuse.
And only one surviving Twilight? I don’t know it was just one more drawing and the recent rain of publications from MLP Infected, the proposals are interesting but I am more into the apocalypse due to a war or magical things (it can be seen in my drawings of Dahs xd), I am not a lover of zombies or infections so I don’t think he would do something like that, but war chaos xd
