After dinner (a lovely rock soup) Limestone, Marble, Spike, Trixie, and Winona all discussed their plan to catch whomever was responsible for the vandalism around the rock farm. In the end, it was decided that everypony would split up and watch specific areas of the farm where it was most likely for somepony to try and break something. Trixie would watch the silo, Marble would keep an eye on the windmill and the house, Limestone would patrol the quarry with Winona, and Spike would watch the fields.
Time passed slowly for everypony. For the longest time, nothing happened. Spike did his best to keep his attention on things, but he'd have been lying if he said he wasn't bored to tears. Limestone kept an eagle eye out for any movement that wasn't herself. Marble had hunkered down beneath a bush to keep a silent vigil over her designated area. Trixie paced back and forth, trying to keep the entire silo in her view.
It was Trixie who spotted something out of the ordinary first. A darkened silhouette moved to the door of the silo, pausing only long enough to look around, presumably for witnesses. The shadowy figure slipped through the doorway. Trixie put on a look of determination before rushing to get to the silo before the figure could leave. As she crossed the short distance to the door, she focused her magic to send up a bright ball of light that hung in the sky above the silo. With luck, the others would see it and come running.
Trixie slipped through the doorway as quietly as possible. The silo smelled of dust and oats. The Pie family used the silo as a food storage. Trixie couldn't help but wonder why anypony would settle for rock soup when there were delicious oats in the silo nearby. Not important! Trixie will apprehend this intruder. Trixie gulped.
The figure didn't seem to have noticed Trixie. It shuffled about, moving barrels of oats about. Whoever the figure was, they were strong. The heavy oats were moved quickly and the figure slipped behind the barrels. Trixie knew this was her chance.
"Yaaah!" Trixie cried out as she hurdled over the barrels and onto the back of the figure. Trixie had the advantage, and both she and the figure tumbled to the ground. Both of them rolled about as Trixie fought for the upper hand. Trixie's hat was lost in the tussle. Some of the barrels toppled over and rolled away.
"Hold still!" Trixie cried. Trixie gripped her cape in a magenta magical glow and removed it. With a fluid motion, she wrapped the cape around the forelegs of the figure, tying it into a knot. "Now to see who you are!"
Trixie focused her magic yet again, illuminating the silo. Beneath her was an attractive blueish-gray mare with a striking blue-violet mane. The mare blankly stared up at Trixie, who stared back with a look that seemed to border between shock, embarrassment, and horror. Time seemed to have stopped.
"Hello Trixie. It's been a while." The mare's even voice stated.
