Piotr's Links
Buck is a very enthusiastic fighter! It is good to have such a healthy fighting spirit when you are young. He also seems to have a good appreciation for the arts, joining the book club Piotr and Elfriede founded and listening to Piotr read to him with rapt attention. A good book sure can be immersive!
If there was one word Buck would use to describe Piotr it'd be "добрый". Originally, he'd only joined the book club to spend more time with Dr. Fischer, but no one (including Buck) could've predicted how intense he'd be over learning Russian. Of course, motivation comes in many different forms, and Piotr is definitely a good motivator!
While not in the same field, they are trusted colleagues, constantly trading knowledge and offering new perspectives to each others works. They're very close friends as well, founding a weekly drink-and-read book club together.
