During church when Pat gives his row Life Savers, the woman next to Candy puts a green one in her mouth. The next shot she again puts it in her mouth.
The year is 1978 when Candy's daughter is rehearsing "Hallelujah" on the piano. However, the song didn't enter (and win) the Eurovision Song Contest until the year after.
The roller coaster that Candy and Allan ride is Switchback at ZDT's amusement park, which began operations in 2007. The ride itself did not open until 2015. Furthermore, the roller coaster employs unusual and highly recognizable rolling stock that first arrived on the market in 2010.
