~A year or two later…
"Hey, 'Bow?" asked Thunderbolt, "What's that?" "Yeah," said Rainbow, "Sorry, I haven't been working out as hard as I should be…" Rainbow had just the slightest bit of what looked like a belly. "I don't think that's fat," said Thunderbolt, "Do you think…" "No," said Rainbow, "I don't think… you really think so?" "We'll get an ultrasound, then we'll see!" said Thunderbolt, "You think your wings can still carry you?" "Even if I am, that doesn't mean I'm helpless," said Rainbow, "Heck, I think I'll still be able to do a sonic rainboom!" "I'd suggest against that," said Thunderbolt. "I didn't say I was gonna," said Rainbow.
They flew to the Ponyville Hospital, where they got Rainbow checked. "We'll have your results in a day or so, Miss Dash," said Nurse Sweetheart, walking off. "What do you think?" asked Rainbow. "I think so," said Thunderbolt. "You'd just LOVE to have it happen, wouldn't you?" asked Rainbow. "Well," said Thunderbolt, "Uh… it'd be nice…" Rainbow rolled her eyes.
~The next day…
They went back to the hospital, where they met the Nurse again. "Oh, hello again, you two," said Sweetheart, "We have your results, by the way." She gave Rainbow a little paper. "I was right!" exclaimed Thunderbolt. "You were right," said Rainbow, "Okay, be prepared to be a father!" "I wonder what we should name him… or her…" said Rainbow. "We have months to figure that out!" exclaimed Thunderbolt, "You can rush a lot of things, but I don't think even you can rush a pregnancy." "Celestia knows I'll try, though," joked Rainbow.
Wait a little for the next book, not sure what it's going to be titled, but it's going to be awesome. Trust me on this one! It'll be about their foal(s!). Cool? I thought so.
