It was a bright and sunny day on Sodor, with all of Sir Topham Hatt's engines hard at work. Twilight Sparkle, now an experienced engine driver like her adoptive brother Spike, whom was at home at the time, was in Thomas's cab, the both of them laughing and bashing trucks in the yard. The trucks let out shouts of protest, their eyes spinning around. "Ow! Watch it, Thomas!" One cried. Thomas chuckled nervously. For some of the engines, the trucks behaved. Thomas heard a whistle and saw James and Rarity pulling passenger train into Knapford. Thomas blew his whistle to James, who whistled in reply. Twilight waved to Rarity, who smiled and waved back.

    "Sure is a grand day, huh Twily?" Thomas asked. Twilight giggled.

    "Sure is, Thomas." She agreed. "Sunny, high of 72 degrees, no clouds. Perfect, sunny day." She smiled. Thomas laughed and reversed down the siding to let Gordon and Rainbow Dash through with the express. They waved and whistled as they thundered by. Thomas whistled back to Gordon. "Besides, work is getting done right on time, just like Sir Topham Hatt asked." Twilight added. Thomas chuckled and sighed. "What is it?" Twilight asked.

    "Hmm?" Thomas replied. "Oh, nothing. Just thinking." Thomas said. Twilight was skeptical.

    "Uh huh, you're thinking about Lady again, aren't you?" She asked. Thomas's cheeks flushed a bright red.

    "What? No!" He exclaimed in protest. "Besides, Lady has responsibilities on the Magic Railroad." He added. Twilight let out a small giggle.

    "Someone's got a crush." She teased. Thomas scoffed and wheeshed steam in Twilight's face, fogging up her glasses. "Thomas!" She cried. She sighed as she wiped the fog from her glasses.

    "Oops." Thomas said. "Sorry, Twilight." He apologized. Twilight sighed.

    "It's fine. I was like that when I had a crush on Flash." She admitted. "Right now, he's out doing his song career." She smiled. Then, a high pitched whistle pierced the air, and a dark blue Fowler 4F locomotive with a 0-6-0 wheel configuration chugged into the junction, his smile bright and beaming.

     "Well, hello, John." Thomas smiled. I smiled back.

     "Hello, Thomas." I replied. "Hello, Twilight." I said to the both of them. Twilight smiled back in reply. "Lovely weather today, huh?" I asked. Twilight nodded. The signal flipped green. "I'd hate to cut the chat short guys, but I've got a goods train to collect. See ya at the sheds!" I called as I chuffed away, blowing my whistle. Thomas blew his back in reply and chuffed down the junction through the station to collect Annie and Clarabel. I backed down my train slowly, stopping to where the guard could easily couple the train up to me. My driver, Quillton, looked behind him to see the guard give him a thumbs up.

     "All clear, buddy." He told me. I blew my whistle and began to chuff away, pulling my train of mixed freight. As we were travelling along the line, I noticed an old line leading to an abandoned tunnel.

     "Wonder what's down that tunnel." I wondered. Quill shrugged.

     "Who knows?" He asked. "Could be another entrance to the Magic Railroad." He guessed. Sadly, it wasn't. Inside the tunnel was an olive green class 42 warship diesel, with a dark brown hydraulic claw. His eyes snapped open, his face twisting into a sneer of hate. His claw chomped loudly, causing me to jump and apply my brakes. Quill was startled and jumped.

     "What in Sodor's name was that?!" I shouted, my eyes darting around. We glanced around for about another minute when a flash of ovlive green thundered by us, his claw chomping furiously. My eyes widened in fear. "Quill." I said finally, swallowing. "Please tell me that wasn't who I thought it was." I gulped. Quillton gulped as well.

     "John, let's hope it wasn't." He told me. I hoped as well. Whoever that was, his color and shape were all too familiar. Thomas had told me about a very engine like that. His name I didn't want to say, because it brought fear into every single engine on Sodor. You want to know his name? Well, his name is......Diesel 10, meanest of the mean, baddest of the bad, and the most evil and psychotic monster to ever roam on the Isle of Sodor, and I was positive that he just thundered by me and Quillton, back for revenge.
