Mr. C [narrating] : And by the way, I think that you're going to help me and Thomas somewhere in this story. Thomas : Ooh. If Diesel has unfinished business, there's sure to be trouble right around the corner. James the Red Engine : [a fly buzzes in front of him] Sandal, fly! Boot, fly! Shoo, fly! That's it! [Thomas shows up] Better still? Buzz off! Thomas : [hits the buffers too hard] Botheration! James : You weren't concentrating, Thomas. Lucky for you that the buffers were there. Thomas : That's what buffers are for - to stop engines from crashing. What are you doing in the sheds, James? James : I'm feeling a little blue, which isn't so hot when you're red. I was naughty, and Sir Topham Hatt told me to think about all the ways I can be really useful, then I could come out again. Thomas : He's just trying to make this a better railway for steam engines. James : [notices Diesel 10] Uh... Thomas : Sir Topham Hatt says... James : Thomas...? Thomas : ...The harder we work, the less he'll need Diesels to help. Diesel 10 : Help you? [chortles] Thomas : Oh! Diesel 10 : You always need help. Because steam engines are cowardly, cranky, worn out hunks of metals who couldn't hurt a fly! James : [scoffs] No, we're not! Diesel 10 : Yes, you are! James : Aren't! Diesel 10 : Are! Now, I've come back to find the lost steam engine. James : What? Diesel 10 : I'm gonna destroy her and dominate you, and then you'll be nothing but useless scrap! [to his claw] Right, Pinchy? James : Big bully! [Diesel 10 laughs and leaves] STINKER! Thomas : We're really useful engines. You won't dominate us, and you won't destroy her. We won't let you, neither will Mr. Conductor. I'm off to fetch him now! James : What lost engine?
