Plot hole: Season 3, Episode 18: Tess sends Jack an airline ticket to visit her in Australia. The ticket reads 'From: Eureka, Oregon, To: Sydney Australia.' Seems odd that a commercial carrier would have a terminal in the most secret town in America. Very few non-residents even know of its existence.
Plot hole: In the episode "One Giant Leap" Allison Blake gets sent to Titan after Jack fails to stop the launch of the Pegasus, but in the next episode ("Do You See What I See") she is suddenly back with no explanation of how she got back from Titan. Also Jo was suppose to have left Eureka to do some soul searching and find her way and she is back as head of GD.
Factual error: Henry Deacon says people only use 10% of their brain at any one time. That's complete garbage - at times we may use quite a small part of our brains, other times the whole brain lights up with activity. The "10%" myth has absolutely no basis in fact - no-one even seems to know where this figure came from! Given the intelligence of Eureka's residents, Henry (and indeed others in the room) would know this.
Continuity: Series 1, Episode 9: Primal. As Carter and Taggart are crawling through the access tunnel, the torch attached to the side of Taggart's goggles is pointing downwards, below his line of vision as established by the lenses on the front. As the shot changes to a close-up on Taggart, the torch is now pointing forwards, aligned with the lenses.
