first off, apologies if this has already been covered, i`m pretty new to these boards.
Right, in the end of season 5 it was faraday's idea to use the nuke to stop the incident and therefore "reset" the island. my question is after being stuck in the 70`s why did he wait 3 years before having this brainwave and decide to do something about it? I know its been written so that it coincided with the return of jack et all and to set up a season finale. but using his logic, if he had detonated the bomb at any time it would have wiped out the island inhabitants and therefore the swan wouldnt have been built, therefore no incident, no requirement to press the button, desmond wouldnt have missed it and oceanic 815 wouldnt have crashed.
Also i dont understand why faraday would want to "reset" the island. sure he loast charlotte etc but i`d assume that working as a researcher with dharma wouldve been a great job for him. also he couldve made a lot of money in new discoveries.
