Alone Season 2: Nicole and her kids

Really liked Nicole and she seemed incredibly knowledgeable, but her leaving because "my kids really need their mom back" was bullshit. She was there almost two months, there's nothing pressing that her kids needed in month three that they didn't have in months 1-2. Does she think her kids could have used her more than the $500k that she could have left them in her will? Just be honest and say you are leaving because YOU need your kids. What a copout.
