Izzy's often straightforward and any line of questioning she doesn't like will be stopped dead in its tracks. But she's worried about coming off too defensive or hostile. So she jokes about things instead hoping the situation will disappear on its own. But this almost never works and it makes her look more suspicious than just shutting things down from the start. Which leads to times like this. 

Also, sorry for not mentioning this earlier but we're dropping down to one update a week. I want to keep a steady stream of pages going instead of going on hiatus. We'll update every Friday for the time being. I hope that won't pose too much of a problem.
