Other mistake: When they show the comic book and Hiro looks up the artist's address, it is listed as 215 Reed St. 7. The door to the artist's loft says his address is 681. (00:01:10)
Other mistake: Captain Eureka losing his finger makes absolutely no sense. He doesn't cry out in pain, there's no blood, and where the finger ended up is completely illogical. The finger didn't just sever on its own; it's shown that severing only occurs when passing through objects. Captain Eureka goes through a wall that is a good fifteen feet away from where the finger is discovered, and it is implausible to think it could have rolled there on its own.
Other mistake: The T.V. begins to work and you see a Chinese man with a map of the United States behind him. The cities that were destroyed were bulls-eyed on the map. Wichita was not bulls-eyed on the map, but Emily seconds later is crying in a car saying that her fiancee is dead because Wichita had been hit and she "saw it on the map."
