Izzy hasn't really let herself cry while living out here. And it's not that Izzy is against crying. Crying is possibly the only display of emotion she's okay with outside of being visibly happy. But she became less comfortable while being out in space. She didn't want to seem like a hassle that's more trouble than she's worth. So okay to cry once in private. But can't make a habit of it because then she starts to look like an issue. And nobody wants to be constantly dealing with an issue. At least in Izzy's eyes. 

So now is time to really let her tears flow.
