A pilot and an instructor knock out a BFR six months ago. Today, the instructor informs the pilot that at the time of the BFR six months ago, the INSTRUCTOR'S BFR had lapsed, which seemingly renders the pilot's BFR null and void. Assuming this is an honest oversight on the part of the instructor, and aside from the pilot needing a BFR, pronto, what is the appropriate course of action for the pilot concerning all the hours logged in the last six months?
