What if this mother were trying to escape Godzilla who was nipping at her heels the whole time she was rushing to the airport because the child had an alien creature lodged in it and she was trying to get to the only hospital in the world who could get the necessary supplies from outer space to heal the baby?
And what if the flight attendants were actually the CEOs of a large corporation that was trying to overtake the world, but the only way they could keep all their plans under wraps was to pretend to be lowly employees on an airline until the battle cry was uttered, and they rushed into place as the kings of the universe?
Sorry, but it's just that there's suddenly become so much "supposing" in the thread as to the motives of each of the parties involved that I figured I'd get into the game as well! Y'all, all we know is what we know from the story. To "suppose" other details that aren't there is just that - supposition, which may or may not be true in the situation involved.
Suddenly, we have the baby dying of a deadly disease unless the mother gets to her destination quickly. We have the flight attendants with bulging eyes and/or talking normally but forcefully. The truth is, WE DON'T KNOW THE FULL STORY. No one does. Because each part of this story comes from that person's perspective only! Including the OP's!
(Just wanted to make sure everyone was still aware of this!
