Invasion

Derek calls Kira and Jesse as Marcia & Greg. This is in reference to step-siblings on the infamous Brady Bunch.

Dave refers to the 1972 movie Deliverance in two separate scenes. In the swamp near the site where Kira's mother died in 1996 (her father Sheriff Underlay was the only survivor on the plane), Dave begins mimicking the Duelling Banjos song from Deliverance. Later at the campsite, Dave tells Jesse and Russell "This is just like Deliverance." In the movie Deliverance, four urban men go on a rafting trip down a backwoods river where they encounter hostile country folk. The movie received an Academy Award nomination for Best Picture and John Boorman was nominated for Best Director.
