Darien Lambert was born on August 17, 2160 but the tombstone has the year 2157.
Darien says the thermite bomb in Kay's car is powerful enough to take out her house and the guest house he is staying in, yet when the car blows over the cliff, the explosion is not only not powerful enough to do what he claimed, but the majority of the car is in tact. Had the car had that much explosive firepower in it, it would have been blown into small pieces.
