Very strange situation. I tend to agree with Am Fear that legal concerns might have been involved but in quite a different way. The couple may have been worried about the liability to the owner of the maze caused by destroying part of it to escape. Its not much a a maze when there is an exit cut through the corridors. It would have been a passing thought, but I would have done it anyway if I considered it an emergency situation (hard to say with a three week old involved). Then again, I may be giving them way too much credit.
