Who was shooting at them on the outrigger????????????
Unanswered LOST Questions - YouTube
A lot of these questions are bullshyt, some were answered or heavily implied.
As much as I enjoyed the fan culture, this was one of the issues I had with it....people became ultra petty with the theorizing, and it got to the point where trivial matters became more important that character development or pacing.
For instance, "Who built the four toed statue?" We saw, when the survivors were jumping through time (I think it was the episode where Charlotte dies, maybe not though), that at one point, the statute was a giant Anubis looking thing. We also later find out that their were different groups, at different times, living on the island (Jacob, his brother, and his mother for instance). It's clear that one of these past groups built the statute...people eventually started asking for too many explanations like this.
Yes, there were some plot holes when all was said and done, but I've never understood "Where are the ANSWERS". The major issues of the show we're eventually resolved.
