Nyx and Teotle faced Scarlet Rose, who had been possessed by Shadowflame. the monsters she had enslaved were on the rampage across Canterlot. Celestia, Luna, Cadance, Shining Armor, and the royal guard had let all the citizens into the castle doors where it was safe and were now fighting off the enemy to keep them from destroying the city.
"Do you really think your parents would want you to attack Canterlot and add to the body count?" Nyx asked.
Scarlet snarled and replied, "They would want our people to be safe. They would want Shadowflame and his conspirators stopped in their tracks."
"You don't know that." Teotle argued.
"Do you?" Scarlet growled. She took out her bow and arrow and prepared to aim. She then whispered, "Prove it."
The shot had been made, sending an arrow straight into Teotle's left hind leg. Normally, he could have stopped or dodged the arrow, but Shadowflame's dark magic gave speed and accuracy to Scarlet's arrows.
Teotle fell to the ground with a hard thud, bleeding out fast from the arrow that stuck out of his leg. Nyx tried to tend to it and pull the arrow out, but Scarlet aimed another arrow at her and said, "Touch him, and you both die."
"I'll never listen to you." Nyx barked.
Scarlet smiled and said, "So be it."
"WAIT!" Teotle yelled, stopping Scarlet from taking the next shot to Nyx's head. "If it's me you want, then take me. Just leave everypony else out of it."
Scarlet raised and eyebrow and asked, "You would die for these lesser beings?"
"No." Teotle answered. "I'd die for my friends."
"Teotle?" Nyx asked in disbelief. "What are you saying?"
"Nyx, go help the others fight off the monsters. I'll deal with my sister."
Nyx's mind did a back flip trying to trying to process what was being asked of her. Teotle wanted her to leave him at the mercy of his vengeful sister, who had the power to command an army. And on top of that, he had an arrow in his leg.
"No, Teotle. I can't just..."
Nyx's words were cut off when Teotle gave pulled her into a hug. It was the most gentle and sincere embrace his small fluffy body would allow.
He then looked Nyx in the eyes and gently said, "It's alright, you can do this. With you there, the others will be able to get out of this alive. I believe that."
"But Teotle..." Nyx argued. "She'll kill you."
"Then she'll get what she wants and leave Equestria alone." Teotle said. "Nyx, you are the best thing that ever happened to me, in all these years, Thank you."
"NO!" Nyx protested with tears coming out of her eyes. "Don't say that. I refuse to..."
Teotle gave Nyx a kiss on the forehead and said, "Goodbye." He then cast a teleportation spell, sending Nyx in the center of the city, where the princesses and Shining Armor were fighting off the remaining enemies they haven't yet restrained or chased away.
Nyx was left dumbfounded by what just happened. Her best friend had stayed behind to fight Shadowflame incarnate alone. Teotle knew it was a suicide mission. He knew he couldn't win with a injured leg, and yet he chose to do it anyway. Nyx was thinking about it so hard that she couldn't move. Her heart felt like it had stopped. She couldn't even hear her aunt Cadance yelling from across the town square.
When she finally snapped out of it, she heard Cadance shouting, "LOOK OUT, NYX!"
Nyx looked behind her and saw an ursa minor standing over her with it's claws hanging far out of it's paws. It attempted to strike Nyx down, but Shining Armor used his magic to hog tie the ursa's paws together, rendering it unable to move.
"Nyx, how did you get here?" Shining Armor asked. "Where's Teolte?"
Nyx was silent for a while, but when she finally had the courage to answer, a flash of light appeared on the street where she and Teotle confronted Scarlet Rose. It was big and bright, and it radiated a very powerful magic. The magical sensation shook the ground and filled the air with an aura unlike any other.
"What is this?" Asked Cadance.
"Nyx's eyes widened with anticipation as she answered, "I bet I know."
