“So What?"
Nothing could be seen past the white wisps of fog that covered the streets and buildings of the city, though the substance itself warmed all who walked through the fog from chilliness that had plagued the town. The girls, now missing Fluttershy and Rainbow Dash, carried on forth to reach the distant castle.
“I don’t get it, Twilight.” Applejack finally decided to walk side by side with Twilight in front of the pack. “Usually the streets are packed with ponies going about their days, but it don’t even look like their hiding away inside their homes.”
“They’re there,” Twilight replied as she tried to charge more energy into the glow of her horn. “Someone has placed a concealment spell on most of the homes that hides any body signatures inside of them. What I’m more worried about is where all this fog came from, as it doesn’t really feel like fog, and winter already passed a few weeks ago.”
“I guess you're right, Twilight. For fog it does feel awfully war—”
A siren off the distance blared its sound down every avenue that the city had to offer, its pitch reaching the highest decimal before lowering to the lowest in the next few seconds. The force of the sound seemed loud enough even to clear away some of the fog.
“This confirms it!” Rarity cut the distance between her and Twilight and Applejack. “There is indeed something very awful attacking the castle that requires our support, which we may now be unable to give fully.”
Twilight glanced backward amongst the fog filled street bearing no traces of any oncoming ponies that may have been her friend. She then looked upward, to the play where her other friend had flown across, unable to see past the thick barrier that barred her from seeing the sky.
“It makes me a little nervous that we may be going against a threat without the full support of the girls.” Twilight trailed her eyes along each of her friends to establish a connection between all of them. “But whatever’s attacking the castle has already weakened the Princess and called for a full retreat for citizens to return home. I...I can’t chance it. I can’t chance to wait behind for the other girls to return when something grave can happen to the Princess.”
“So what?" Applejack swirled around to the front of Twilight’s vision, blocking her from seeing any of her friends. “You proposing we just leave em behind for somethin to happen to em?”
Twilight shook her head as she retreated a few steps into another case of steps, establishing that precious connection with her friends that connived she felt as much as stress at the notion just as much as they did. “Whatever’s attacking Canterlot has no clue that we’re here yet, so it shouldn’t attack any of our friends. The siren that’s almost making us deaf should be heard by the other girls, so if they can’t find us in the streets, then they should know to trying going there next.”
Applejack bit her lower lip in thought as she closed her eyes, heaving a heavy exhale upon their reopening. “Fine. Though if we hear anything about our friends falling into harm, then I’ll be the one storming away from the fight to go save them, capeesh?”
Twilight nodded, before turning around, and dashing through the fog covered streets to reaching the blaring siren.
