I don't believe that can be said for sure. Seems to me that could be a result of individual tolerance, not gender-based tolerance.
RE: Thinking
Pegs was pregnant, I think we all jump there because we expect Lizzie to be preggers. At most, one will be pregnant. Otherwise, you've got two
characters with the same dilemma, and that makes one superfluous.
RE:
Saul leaving...silly move that is great for plot. Also, it is a great way to get back to Lizzie's situation. Definitely
Burt's chance at redemption by going after Saul, and may lead to his death.
Overall, I love that there are a number of plot lines that have opened up. The fact that
Ground Zero has been introduced makes me wonder where the helicopter plot line will go. The copter plan is supposed to take them a long way from Ground Zero, but GZ seems too big a situation to deal with in only one chapter.
