Monica Reyes: Due to their decision to continue "The X-Files" television series and try to appeal to a new generation of viewers, the production personnel knew from the beginning of season 8 that they were going to introduce another female character who would be a believer, as departing character Fox Mulder (David Duchovny) had been a believer.
