Why didn't he just stay?

There was some trouble at the U yesterday and apparently some of the classrooms were vandalized. Even Dr LaRue's lab! And I am thinking it's too random not to be connected to whatever dad's doing. And it has me a little worried. But not as worried... look, I'm not mad at my Mom. It's not... completely... her... fault... that she's pregnant... but she didn't have to agree with Dad about him going away. If she didn't let him go or she didn't waant her to go, then he wouldn't have gone and left me here to take care of 96 sisters and a pregnant mother. He could have just stayed until... the baby came. Which will be soon. I feel sick.
