Quotes

"What's wrong guys?"
"Oh, nothing. We're just a little homesick."
"But, Ms. Sierra, how could you be sick of a wonderful place like Sodor?"
"No, Toad homesick means that we miss our home, not that we're sick of yours."
"Oh, sorry, Mr. Jacob."
"That's alright, Toad. After, all you gave us a good laugh.

"I don't think it's very wise of Mr. Hatt to leave those two immature children in charge of us."
"They're not children anymore, Marie. They're 16 now."
"And anyway, they've been on Sodor, taking care of themselves for like 3 years now. I think if they can take care of themselves for that long, then they can certainly take care of all of us for a week."
"They're still young, and they surely aren't responsible enough to take care of a railway as big as this one."
"I hate to admit it but, Marie’s right. This railway should not be left in the hand of two incompetent and irresponsible children.
"
