chunk: Separate, but related, story arcs, which revolve around the employees of Lacuna, are revealed during Joel's memory erasure. Patrick, one of the Lacuna technicians performing the erasure, uses Joel's memories and mannerisms to seduce Clementine. Mary, the Lacuna receptionist, is dating the other memory-erasing technician, Stan. During Joel's memory wipe, Mary discovers she had previously had an affair with Dr. Howard Mierzwiak, the married doctor who heads the company, and had agreed to have this erased from her memory when Dr. Mierzwiak's wife found out. On learning this, she asks Stan whether he knew about this, to which he claims that he didn't. Mary then quits her job and steals the company's records, and mails the two former clients their records from Lacuna.
