The glyphs at the ad breaks spell "observer".
There are eight pictures that appear when a commercial break is coming or for promoting the show. They are:
- APPLE: the seeds in the apple are human embryos.
- BUTTERFLY: the wings are made up of bones.
- FLOWER: some of its petals are dragonfly wings and the center shows a Fermat's spiral.
- FROG: has a symbol on its back for PHI.
- HAND: it has six fingers.
- HORN: has the Fibonacci spiral and has the number of PHI inscribed on the horn.
- LEAF: has the delta symbol in the middle of it.
When John and Olivia share consciousness, at the graveyard, on the headstone to the right behind Olivia, the inscription reads "He's not dead".
The engines of the plane have the Massive Dynamic M-cube logo in the center of the turbines instead of the usual off-center dot.
Olivia says that Peter's IQ is "190, just 50 points north of genius." Indeed, an IQ of 140 would be higher than 99.3% to 99.6% of the human population, depending on which IQ test was administered. In comparison, Peter's IQ would be higher than 99.9999990699% to 99.999999901% of the human population.
