Proudfoot
I doubt it. He has changed significantly since we were childhood best friends, and although he welcomed me back from being on the run with open arms, there was a very quick turn around in which he seemed to become... obsessively paranoid. I'm not sure how to phrase that more politely.
I grew up as a muggle, and my father and brother were both quite athletic. Before I went to Hogwarts, fencing was a past time that I shared with them. If you'd like, I could teach you in exchange for your help with my animagus studies.
