So, if Lorca is from the mirror universe, did he intentionally chart coordinates that would ensure his return home? Fans clearly saw him override the coordinates for Stamets' final jump in the spore drive, so there's definitely something up. It's enough to make one wonder if, when Admiral Cornwell exclaimed Lorca "wasn't the man she used to know," she was unknowingly stating the truth. Is it possible the mirror Lorca killed the original Lorca during the explosion of the USS Buran, and is now living his life? Have all of Lorca's efforts in perfecting this spore drive technology all just been about getting home, or was he just waiting to get that cloaking data before making the jump?
