Suggestion for slight rewording and I don't think the describe(TravelMethod) is needed here.

Suggested change

	The `describe(Character, Destination)` method should reuse the logic implemented in `describe(Character, Destination, TravelMethod)` or in the individual methods `describe(Character)`, `describe(Destination)`, `describe(TravelMethod)`.
	The `describe(Character, Destination)` method should reuse the logic implemented in `describe(Character, Destination, TravelMethod)` or in the individual `describe(Character)` and `describe(Destination)` methods.

I think the describe(TravelMethod) is actually needed. In fact, the method describe(Character, Destination) can be implemented in two ways:

1. public String describe(Character character, Destination destination) {
   return describe(character, destination, TravelMethod.WALKING);
   }

2. public String describe(Character character, Destination destination) {
   return describe(character) + describe(destination) + describe(TravelMethod.WALKING);
   }

Without referring todescribe(TravelMethod), the student may think that one solution is also:

public String describe(Character character, Destination destination) {
return describe(character) + describe(destination) + "You're traveling to your destination by walking.";
>}

Also in design.md, they suggest to indicate it.

Oops, you're right! The describe(TravelMethod) is needed here.

Looks good to me now.
