regarding Jon's Poll question:
Jon's douche-ness is a reaction to Kate's bitchiness. He was an abused spouse for 10 years, under her thumb, verbally and emotionally abused (if you think this isn't true, reverse the genders here and then decide).
He escaped, realized he was free, and his extreme douche-ness is now coming to the foreground. He may have been an ass before he married Kate, but he was unable to show it for 10 years. Now that he's free...all bets are off.
Both are equal in their displays of irresponsible behavior, selfishness, and greed.
