When Hurley brings his mother to her new house, the blindfold is folded differently between scenes.
When Hurley picks up the cable that runs across the beach to the water, there are clearly fresh footprints following the cable up to the bush line.
When Charlie is crossing the rope/plank bridge, he steps on the same plank twice.
Sam Toomey believed that he was cursed after using the numbers to successfully guess how many beans were in a jar. That's nearly five billion beans (4,815,162,342). It seems unlikely that this many beans could fit in any jar. However, all that's known is that Toomey "used the numbers". It is not known in which way, so assuming there were almost five billion beans involved is rather outlandish.
Whilst lifting up the cable, a white sailboat is visible over Hurley's right shoulder.
