Spike had just arrived from the portal safely. He looked around and noticed where he was. “The Everfree Cave? Rainbow Dash should be here. I hope she saw my message...” Spike ran out of the cave to find the Treehouse of Harmony. He quickly ran inside. “Okay, the Treehouse of Harmony is here, but where’s Rainbow?” Spike started to worry. “I hope Rainbow is okay, but I have a feeling Twilight hunted her as well...”

Cozy Glow appeared in the cave tired. She looked around in confusion. “W-What is this place?” Cozy didn’t recognise this cave, but up ahead she saw some strange crystal-like treehouse. “Maybe I’ll be safe in there.” Cozy flew to the Treehouse of Harmony and entered. The moment she did, Cozy found two of her worst enemies. Spike noticed Cozy Glow. “Spike?”
“What are you doing here Cozy?” Spike asked.
“Same as you, I suppose...”
“Twilight tried to kill you too, right?” Cozy nodded. “I hope Rainbow Dash is okay too...”
“Rainbow?” Cozy asked. “Do you think she’s in danger?”
“Yeah, but I think she’ll be okay.” Spike said. “She is a tough pony after all.”
“I’m afraid that’s not the case..” Spike and Cozy turned to see a glowing version of Twilight Sparkle.
Spike took a close look at the figure. “You’re not Twilight are you?” The figure shook her head. Spike thought for a moment. “Wait! Smolder told me about you! You’re the spirit of the Tree of Harmony!” The figure nodded.
“What!? I thought the Tree was destroyed by Sombra!” Cozy said.
“As long as friendship exists, I exist.” The Tree’s Spirit said. “I’m also the one who brought you two here.”
“That was you?” Cozy asked. “You even saved me? After everything I did?”
“It wouldn't be right to just let you die.” Harmony answered. “Besides, even you deserve a second chance. But I’m afraid your friend; Rainbow Dash is dead.”
“No.” Spike simply said. “How could this happen? Do you know what caused all this?”
“Yes, take a look.” Harmony glew and the two survivors saw the meadow. Twilight was looking at her watch then looked up. Suddenly, a black gas flew into Twilight’s mouth. Twilight closed her eyes, shook her head and opened them back up to reveal black eyes with red dots. The vision ended.
“That explains it!” Spike exclaimed. “Twilight would never try to kill anyone!” Cozy turned to the spirit.
“Are you saying that Twilight’s been possessed?” The spirit nodded.
“Well, what do we do next?” Spike asked. “We have to get her back to normal somehow!”
“I remember AppleBloom telling me about a secret base in Vanhoover which is heavily fortified.” Cozy said.
“Then it’s settled.” Spike said. “We’re going to Vanhoover!”
“Very well.” The Spirit said. “But one more thing.” The Spirit turned to Cozy Glow. “Cozy, you’re going to need a little boost just in case.” The Spirit aimed her horn at Cozy and fired a beam. After the smoke cleared, Cozy came out revealing bigger wings and a horn.
“I-I’m an alicorn again!?” Cozy said with shock. “W-Why!? Last time I nearly-”
“Trust me, you’ll need it Cozy.” The Spirit stepped between the survivors. “Okay! I’m now sending you to Vanhoover. Good luck!” The Spirit glew and in a flash; Spike and Cozy Glow were gone.
-----------
Spike and Cozy Glow appeared in Vanhoover.
“Okay Cozy, what now?” Spike asked.
“There should be a device hidden in the laboratory.” Cozy answered. “It can help Twilight.”
“How do I get there? Do you have a map or something similar?”
“I’ll ignite a blue light bulb for you.” Cozy said. “That’s a door.”
“Okay, see you there!” Spike said before flying off.
-----------
Spike was walking down a hallway of the secret base and stopped when he heard Cozy’s voice.
“Spike, where are you?”
“I’m in the White Hall. Like you said, through the door with a blue light.” Spike answered.
“I said through the door with a yellow light, not blue!”
“No, I recall you saying the door with a blue light.” Spike countered. The lights suddenly turned off. “C-Cozy? What’s wrong with the lights?” Cozy coughed in response.
“I’m having a few problems… I’ll call you later.” In the lab, Cozy was watching the monitor and trying to avoid the terrible smell. “Okay, I’ll press the button to open the ventilation shaft.” Cozy reached for the button, but paused and thought for a second. “On second thought, I won’t.” Cozy began to look at Spike on the monitor. “Spike, we have a problem. Twilight is here… I see her through the cameras.”
“This is bad!” Spike said. “Wait, she’s in Vanhoover right? Nowhere near this hidden lab?”
“No, she’s near you. That’s a big problem.” Cozy answered. “Don’t worry though. I can see everything from here; both you and Twilight. Go forward.” Spike began to move. He walked for 7 seconds. “Stop.” Spike stopped for 4 seconds. “Go forward and left.” Spike continued his way down the hall for a good 14 seconds. “Stop.” Spike paused again. After 10 seconds, Cozy spoke again. “Go forward, you’re almost here.” Spike continued walking down the hall. “Stop. She is right in front of you. Don’t. Move.” Spike nervously stayed put. “Go forward, she is behind you now.” Cozy said after 15 seconds. Finally, Spike found the lab entrance.
“You’re alive! Don’t worry, you’re going to be fine now.” Cozy reassured Spike.
“Thanks, but what do you have now?” Cozy lowered her head in response.
“I-I’m sorry Spike. I don’t have a device that can help Twilight, for now. I found a teleporter.” Spike stared at Cozy with betrayal.
“Y-You lied to me!” Spike said. “How could I trust you? You want Twilight’s death!”
“Come on. This is no time for that.” Cozy said as she pressed a button and she and Spike teleported away.

(Outside of Equestria)
Spike and Cozy Glow were now in a location none of them had ever been to before. They turned toward the sunset.
"If you want my help… promise me that we’ll save Twilight." Spike said.
“If we don’t die... I promise. When this is over, could you give me a chance to make up for all I’ve done?”
"Sure." Spike said as the 2 of them viewed the scenery.
