 The dialogue in all releases of the movie alludes to another  replicant who dies before Deckards final battles with Pris and  Batty. The conflicting dialogue occurs in the first conversation  between Deckard and Bryant. Bryant initially tells Deckard there are  four "skin jobs" on the loose, but minutes later says six escaped,  and one was killed by the "electronic gate", which should leave  five. The explanation is that the script originally contained an  additional replicant named "Mary", but time and budgetary  constraints resulted in her being written out. M. Emmet Walsh (qv)  who plays Bryant, reports that new dialogue was recorded to change  the number of replicants in this scene, but Scott inexplicably only  used half of the new dialogue, resulting in the inconsistency.
