Question: In this episode they are digging the hole to get through to 'Scylla', when digging the hole the concrete bar drops or something. Brad goes in to the pipe help but he can't get out in order to get them to Scylla, so therefore he is left in there to die. That tunnel though is the source of the water to L.A. So there would be a dead body in the water and everyone would be drinking water where a dead guy was, am I right? Or did I miss out on something?
Continuity mistake: On the tombstone in the previous episode, Michael's date of death is 11.4.2005. But in this episode, when Linc goes to the graveyard to visit Michael's grave, his date of death is 11.4.2010. It is also a different grave from the original, as the original was in South America beside the beach, and here we are led to believe it is in New York. (00:50:50)
