"Ha!" Twilight laughed. "Forget it, Trixie. I'm not going to fight you. I have nothing to prove."
"Perhaps not, Twilight Sparkle," Trixie sneered. "But Trixie does." She pointed her horn at Spike and fired a blast of magic, hitting him squarely and turning him into a small lizard.
"Spike!" Twilight shouted. "Change him back!" she demanded.
"Make me." Trixie said, taunting her.
Twilight just glared.
"Trixie will simply continue tormenting your friends until you agree to fight her." She pointed her horn at another pony as it began to glow.
"Stop!" Twilight yelled, causing Trixie to turn back to her. Twilight looked at the ground angrily and sighed, then stared Trixie in the eye. "So that's what it's going to take, huh?" she said, the anger dripping from her voice. "Very well, Trixie. You leave me no choice. Just remember, you brought this on yourself, because I'm about to kick your sorry flank."
"Bring it on, Twilight Sparkle," Trixie said with a grin.
The two unicorns' horns both began to glow brightly as ponies nearby started backing away and looked for cover. Twilight appeared to be building up to a massive release, but Trixie fired first. Before the blast could hit, though, Twilight disappeared in a flash of purple light. An instant later, and before Trixie could react, Twilight reappeared just behind her and literally kicked her in the flank as hard as she could, sending her, and the amulet she was wearing, flying. Both Trixie and the amulet skittered across the ground, and when they come to a stop, Twilight quickly picked up the amulet using her magic, and in a flash it disappeared.
"No!" Trixie shouted. "My amulet! What have you done with it?"
"That's for me to know, and you to find out," Twilight said, smugly. "I told you I'd kick your flank."
"Give it back! I need it!" Trixie demanded, desperately.
"I thought you might, Twilight said, "Which is why I took it away." Twilight calmly walked over to Trixie, who was still on the ground in shock and pain, and roughly pushed her onto her back, then pinned her with her hooves. This time, only the tip of Twilight's horn began to glow, but it burned with a white hot light, emitting small sparks. She leaned down and stared Trixie square in the eye, her horn uncomfortably close to Trixie's face, causing her to flinch. "So tell me," Twilight said, confidently. "What is it, and where did you get it?"
"Trixie doesn't have to tell you anything!" Trixie said, defiantly.
"As you wish," Twilight said, bringing the tip of her horn closer to Trixie's neck until it began to singe her fur.
"Alright!" Trixie yelled. "You win! I'll tell you everything!"
"That's better."
