Diesel 10 had long since crossed the bridge to the mainland, and was seemingly lost in thought, not caring where Aurora was taking him. Noticing his silence, Aurora spoke up. "You doing OK there?" she asked. When he didn't respond, Aurora let out a sigh and said, "Do you wanna head back?"

"There's something up ahead," Diesel 10 said.

"It's just an old line," Aurora said as they slowed down, "We probably shouldn't go down there. It could be dangerous,"

"But there's something there," said Diesel 10.

"I don't see anything but trees and bramble. Those tracks aren't safe," said Aurora.

"There's something there!" Diesel 10 insisted.

Reluctantly, Aurora gave in. "Alright, we'll go check it out, but don't complain if you come off the rails," she said. At that, they very slowly went down the old line. As it turned out, Diesel 10 had seen something. As they slowly approached, a badly rusted, derelict old steam engine sat on the line, which had clearly been abandoned for many years.

Diesel 10 found himself feeling sorry for the engine in front of him, which made him confused. Why would he feel bad for an old, rusty pile of scrap? After all, this was a steam engine, which he had loathed and despised their kind for many years. Yet, the way this engine stared ahead at him, fearfully and hopelessly, made him think that maybe it was no different from the diesels that get sent to the scrapyard that Daniella lived and worked in.

"Hello?" the engine called out, "You—you're a diesel," she said with a gulp.

Diesel 10 rolled his eyes. "That much is obvious," he said.

"Are you a bad diesel?" the engine said quietly.

"Your kind seems to think so, then again, most of you steam engines seem to think that diesels are the worst thing to happen to the railways," Diesel 10 said bitterly.

"Are you going to take me…to be scrapped?" the engine asked sadly.

Diesel 10 was taken aback. "No, now why must you assume that?! I simply saw something on this old line, and it just so happened to be a rusty old steam engine!" he snapped.

"I'm sorry," the engine said, looking down, "I thought you were out looking for steam engines to scrap…my name's Anna,"

"How long have you been here?! It's been years since steam was abolished, and now us diesels are being withdrawn!" Diesel 10 hissed.

Anna merely looked down, not saying anything more to the big diesel in front of her. Then, to her surprise, Diesel 10 coupled up to her. "What are you—" she said.

"I'm going to help you," said Diesel 10. As much as he had despised steam engines before, this one seemed rather friendly. Not only that, but he simply felt bad about leaving her all alone to rust. However, when he went to move her, Anna's rusted coupling snapped.

Anna sighed sadly, but Diesel 10 was determined to get her to move. Using his claw, he gripped her buffers and reversed. However, this turned out to be a very bad idea. Anna was severely corroded, and brittle. With an ear piercing screech, her buffers came loose and her boiler cracked and separated from her cab. Diesel 10 released her quickly as she let out an agonized scream. He was very upset at what he had done, for he hadn't meant to harm her.

"I—what have I done…I've killed you…" Diesel 10 said, looking down in shame. It was then he finally admitted to himself that despite his anger and grief all those years, he had never truly wanted to kill anyone. He hardly noticed the tears streaming down his face; he was so wracked with guilt.

"Don't cry," Anna spoke softly, "It's not your fault,"

"But—I ripped you apart! I—god damn this claw!" Diesel 10 shouted.

"Hush now. You did me a favor," said Anna.

Diesel 10 looked at her, puzzled.

"Look at me," Anna said softly, "I'm too far gone to be restored. If you hadn't come along, I would have continued to sit here and rust and I would've been all alone."

"But I—" Diesel 10 started.

Anna smiled a little. "I know you were trying to help…in a way…you did," she said, her voice becoming strained. "Don't be sad…it's just my time,"

"I didn't…" Diesel 10 trailed off.

"You're very kind…you're a good diesel…remember that," Anna whispered, before closing her eyes one last time.

Diesel 10 was surprised. He had never expected a steam engine to say that to him, let alone one that he had accidentally damaged. Finally, he headed back to Sodor. His experience with Anna had made him think that perhaps he shouldn't treat the other steam engines as if they were the same ones who had taunted him about his class being withdrawn. After all, he wasn't the last of his class, like he had thought for so long.
