2. There were TV show references galore!
There were some great references to a couple of great TV shows in this episode. Firstly a reference to Lost, when Daryl and Carol set off to investigate the white van teetering on the end of the bridge. They climbed in the van to look for clues but were then forced to tip the van over the edge of the bridge to escape a small hoard of walkers. On the dashboard of the van was a statue of Mary, much like the ones used to smuggle heroin in the show Lost. Like this episode , the statues in Lost were in a vehicle (a plane) that was tipped over, though not off a bridge, but a cliff.
The second reference was to The X-Files. When Daryl and Carol reencounter Noah, Daryl swiftly traps him under a bookcase, and he then sparks up a cigarette as he begs for them to help him. The brand Daryl smokes, Morley's, is the same brand famously chain-smoked by the big baddie in The X-Files, The Cigarette-Smoking Man.
