So your saying that May intentionally took the reins of said stagecoach, and continued to head straight for the cliff, because she wanted to be pivotal?  Pivotal, as in the idiot that drove us all off a cliff?

I firmly believe she's an idiot, but I don't believe that a desire to be pivotal is the reason for her stupidity.  I feel it's likely a much simpler explanation.  It's much more feasible that she believes she can fly.
