Say hello to Blazin' and Luna's filly! She looks older here because Pony Creator Full Version couldn't make her any shorter than this.
So this surprising story begins after Blazin' had been dating Princess Luna (after finally overcoming his shyness) for nine months. Little did Blazin' know that Luna had a little surprise for him which was sleeping under a rosa blanket in her bedroom! Yep, it was her filly, and Blue has no idea he is the father of-Princess Nightshade!
Blazin': *hears the phone ring* Hello...
Luna: Hi, sweetie! Those nine months of dating really benefitted the both of us, didn't it?
Blazin': Yeah, and I'm no longer nervous around you. Even Rarity detto we look cute together.
Luna: *blushes* Oh, well....She's right.
Blazin': Yeah, we do make a good couple.
Luna: Um, Blue, there's something I gotta tell you.....
Blazin': What's up?
Luna: Um, just come see me in my room at the castle. I'll let the guards know your'e coming. Bye! *hangs up*
Blazin': *hangs up* Something's not right. Is something wrong with her?
Lyra sees her brother put on his preferito gamer hat and his Pokemon pendant around his neck.
Lyra: Watcha doing?
Blazin': Something's up with Luna, and I'm worried. I'll see te later!
After three hours of walking, he sees the royal carriage sitting with the two guards at the front pointing to him.
Royal Guard 1: Excuse me, are te Blazin' Blue?
Blazin': Yes, I am.
Royal Guard 2: Luna asked us to take te to the castello so te don't get tired on the way there.
Blazin': *takes a seat* Thank you. Take me there, please.
This ride cut the time to reach the castle, so they arrived in just one hour.
Blazin': Thanks for the lift!
Royal Guards: Anytime. Luna even says she'll ride with te whenever you'd like.
Blazin' makes his way to Luna's room, and Celestia notices him and starts walking with him.
Blazin': It's fine, Your Highness. I'm a lot braver.
Celestia: I'm here to make sure your'e safe.
Blazin': Safe? I'm in a castle, it's pretty safe-
Queen Chrysalis: HAAA!! I'm looking for the blue unicorn with blue fire-like hair. It's come to my attention that he is in Amore with Princess Lun-
Celestia: SHUT UP!!! *knocks Chryssy out a window* Pretty safe, huh?
Blazin': Yeah, except for that time.
The two arrive at the door to Luna's room.
Celestia: I'm gonna let te take it from here. te are my sister's coltfriend after all. *leaves*
Blazin' enters Luna's room to see Luna sitting on her bed, looking quite sad. He looks around and unfailingly sees diapers, wipes, and puledro powder in one corner of the room.
Blazin': Eh....What's going on?
Luna: Well, I....uh....
Blazin': I know what it is-You wear diapers, and te wanted to keep it a secret!
Luna: What? No! Though I do wear some that are my size when playing games for a long time.....And da that I mean my own diapers....That's not important right now.
Blazin': *looks around again, and sees a filly sleeping under a rosa blanket in her bed* Aw, don't tell me!
Luna: Yes. She's our filly. Her name is Princess Nightshade.
Blazin': Does that mean.....
Luna: Yes, I was pregnant at some point da te while were dating. te were gone, helping AJ out at Sweet mela, apple Acres, and that was very sweet of you. Cadance told me prior to solano, nightshade being born, "I wish Blue were here to see the arrival of his daughter, but he's helping AJ, and that's ok, you're gonna mostra him his daughter when he comes back at some point, aren't you?".
Blazin': I didn't mean to do this to you. I was in Amore with te and...
Luna: Shhh...I accept your apology. But let's raise solano, nightshade together. And maybe we'll introduce her to everyone in Ponyville.
Blazin': Sounds good! I better get going now...
Luna: Why don't te come live with me here? I'll help te sposta in with me tomorrow. But te can see your sister Lyra anytime te like. Go on home, te need to get some rest.
Blazin' is dato a ride back home, where he gets in letto wondering how to tell his sister Lyra.
Luna is happy that she and Blue have a filly of their own!
