Guilt
Twilight's P.O.V
I turned my body overy to the mountain. Then I crouch down, and jump super high. Spike held on tightly to my paw as we were soaring through the air. After all, it's very hard to flap these new giant wings of mine. Once I landed in the forest, I lifted my paw up at my shoulder for Spike to climb onto my left shoulder and hold it tightly. Next, I ran on all fours through the forest that now grew during our time in Ponyville.
Meanwhile, back in Ponyville...
Everypony came out of their hiding spots and see what has become of their beloved town. Rarity released her dome spell and sees what happened to Ponyville. Pinkie and Applejack looked all around see patches of flame everywhere. The three mares where horrified of what has become of their home. All of them except Fluttershy wasn't paying attention at all to what happened to Ponyville. For she was looking at the mountain that the creature who held Spike had escaped to. Fluttershy remembered what Spike said to the creature to stop breathing fire. "Twilight?" Fluttershy said as she looked at the mountain, and a storm cloud coming.
Back at the mountain...
Hulklight's left paw held onto a ledge, then she put her right one on the same one. Next, a green spike appeared. Then, the head of the green giant had appeared as well. Hulklight pulled herself up and walked inside the cave. It was still bigger the last time she was there and its still bigger than her. Hulklight moved her tail to the left. She grunted to tell Spike to slide down her back. Spike, not saying a word, slid down her back, and down her tail which was still encompassed by her tail sock. Spike continued walking, but, then he stopped, with his arms crossed.
Spike's P.O.V
I stopped in front of Twilight with my back facing towards her. I pulled my shoulders up a little, and then sighed. "I can't believe you, Twilight," I said while my head was turned to the left, looking at Twilight.
"*Grunts questioningly*" Twilight said confusingly.
I fully turned all the way to the left and pointed my right finger after she said that. "Don't give me that, Twilight. You nearly destroyed Ponyville! Our home! Whatever you did to yourself, I hope you're happy. Because of you, Ponyville's been charred almost to a crisp! Good thing the houses are still intact. Otherwise, you will be the one to blame! I can't believe I have a monster for a sister!" I shouted at Twilight.
Twilight's P.O.V
My eyes started to tear up when Spike said. I didn't even know that the potion would do this to me.
Spike's P.O.V
"I HATE YOU, TWILIGHT!" I shouted at her in anger. Then, I coupled my paws together on my mouth of what I just said.
Twilight's P.O.V
Yep. That did it. My eyes started pourin out tears. "Aaaah ah ah!" I cried with paws elevated at my chest in the form of a dog begging. Then, I crouched and jumped over Spike's head. Then, I ran to my left behind a giant rock.
Spike's P.O.V
I looked in sadness at the direction where Twilight ran with my left paw straight out. I didn't mean to say those hateful words to her. "*Sighs* Why did I say that?" I said as I put my right paw on the side of my forehead. Then, I turned to the left and walked outside the cave. I looked up after I felt something wet has hit my nose. It was drizzling. Then it started raining.
