Here the Haddock living the swordfight happens in a different way. That's where they've derived setups from other books.

Calculus-Haddock is a lot of fun. But again, they've bypassed RR treasure. So whatever you expect from Unicorn, has been changed & merged with plotpoints & characters in other books.

In some ways, it's far more refined here. We don't have Haddock explaining major details to Tintin (like in the book), here he has to "earn" it. And their encounter in Karaboudjan (from Golden Claws) is fit in here seamlessly. Should work for you.
