wipe questions about old star trek episodes from MY mind and there simply wouldn't be anything left, and i would be as blank as Uhura was when her memory was wiped by Nomad, the space probe created by the collision of an Earth probe designed to seek out new life forms, and Tan Ru, an alien probe programmed to secure and sterilize soil samples from other planets, and their two programs merged and create a probe who believed its purpose was to seek out and sterilize imperfect life forms and which then mistook Captain James Kirk as Jackson Roykirk, its creator!
