Ple Two is very much right about that one. Madoka doesn't think fighting a huge orc would go well for either of them, even though Ple Two is pretty good when it comes to fighting. It's just the downsides of being two of the smallest people on the entire train.

"And it's not like we're getting that much taller here either, huh.."

The curse of being on the train. They're both pretty much ageless while they're here, even outside of Ple Two's.. unique situation, let's say.

"But that's why we've got to use our height in ways that work for us! Like fighting from a distance, or.. um.. trying to outsmart enemies, even though I think you're better at that part than I am.."

Madoka isn't exactly a combat genius, after all. Everything she's learned about fighting is just stuff she's learned on the train.
