I was reminded that they switched writer's or something mid-series. I'm wondering if the original writer's had an idea of what the storyline was going to be, focussing quite a bit on Walt and Aaron...and then when the new writer's came on board, they took a different path with the focus of the stories and characters. So we may never really have resolution on some of the main questions from earlier in the series.
But Damon and Carlton have been the main story architects since day one. I think their main story will end up being told to its end on May 23. Some of the questions that we have been freaking out about may not neccessarily be important to the core of the story regardless of how desperately we want it to be. Some Examples:
-Claire's prophecy may have just been forshadowing the island timeline and the fact that she was eventually going to be living in the SideLine
tm with Aaron by her side. "Must not let him be raised by another" and then the inevitability of him buying her the ticket on 815 to crash her on the island and Aaron ends up being raised by another. Course correction.
-Walt's Powers may just be another instance of a character having a special power on LOST. His seemed unique until we meet up with Hurley, Miles, and Desmond. They all have powers of there own. The explanation of this could be as simple as these were powers that were intended for Waltuntil he hit a Power Forward's growth spurt.
-Kate's Horse was one that escaped from the Flame station.
These are all questions that have been asked at one point in time or another, and may very well never be answered. Does that mean that their story arc was made up as they went? No. It just means that they adapted their initial intentions to fit withon the structure of the story they wanted to tell. This is story that is over 100 hours long. There is no way to tell a story that lapses the century mark and is completely devoid of inconsistancies.
