I read somewhere else that the guys in the frozen lab (who were apparently speaking Brazillian Portuguese....or so I've read) actually told her "We think we've found the island", not "We think we've found him".
With how Desmond couldn't find Fiji, I suppose it is a possibility that the Island isn't really an island, but some sort of giant floating thing.
As far as wondering what the "incident" was, I meant the original "incident". It had been hypothesized that the incident was made up to form the basis for the psychological experiment, but as the button really does do something, I would suspect that the incident was real.
