"Oh no..." This was all Twilight could mutter in her now panicked state of mind. It had now dawned on her memory that all this time she spent in happiness with her newly adopted son was the time her friends were away. And now they're all back.
Fang watched Twilight panic but was curious about the new voice he heard.
"We have to hide you. Can you change? Are you old enough to? Oh, I don't know!" Twilight's teeth started chattering as she tried thinking up a plan or excuse. Fang thought on what Twilight said and, even though confused, he changed into a grey Pegasus colt with white patches and light emerald eyes. His mane and tail were as black as his carapace shell. Upon hearing the whoosh of Changeling transformation magic, Twilight turned and saw Fang in the facade of a Pegasus colt. Mental note, jot down this new discovery down later. she thought.
"H-How do I look, mommy? Now I look like you." He smiled timidly.
"Oh Fang, you look adorable." She picked him up and hugged him. "I'm surprised you can change already. I thought you might be too young."
"It feels weird, mommy. But you looked really scared for someone to see me and you wanted me to hide. I thought this would make you happy." He said, nuzzling under her chin.
"Oh sweetie...you didn't have to-"
"Twilight, there you are. Didn't you hear me calling?" Spike asked, walking into the kitchen. He noticed the little Pegasus and cocked an eyebrow. "Who's that?"
Twilight looked down to Fang and smiled nervously. "This is...he's...uh...he's-"
"Hi. I'm Emerald Ace. Y-You can call me Ace. Are you Spike? Mommy told me lots about you." Fang timidly poked the crystalline floor as he looked around from Twilight's side. Fang nuzzled Twilight's leg and looked up to her as if asking if he did alright.
Spike and Twilight blinked in a little shock. Spike was the first to speak. "Mommy? Wait huh? Twilight, what's going on?"
"Well...um..I took in a colt. Fa-er Ace is going to be staying with us." Twilight wrapped her wing around him. "So I guess you can say I have a son now."
"Do the Princesses know?" Spike asked.
"Oh no...I haven't gotten to tell them about him. I wanted Ace to get more situated first before letting anypony else know about him." Twilight said honestly.
"Well, soon the others will know about him since they're all in the map room," Spike said. "I came here to get some snacks for us. This is gonna be a huge surprise."
"You all would've found out eventually. I guess now is a good a time as any. So what do you say, Ace? Are you ready to meet the rest of mommy's friends?" Twilight asked. Fang was nervous about his answer but nodded yes anyway. With that, Twilight made her way with Spike and Fang to the map room to introduce her new son to her friends.
