The original script and deleted scenes reveal that the characters of Mackenzie and Marla Maples were actually fellow employees at an office building before the outbreak, where Mackenzie left her to die while he escaped. She is cornered on the rooftop by zombies before being saved by Carlos and his group only to commit suicide by jumping off the building nonetheless due to being bitten. Mackenzie would meet up with Jill and her group at the church before eventually being killed by a licker.
