I wondered where you'd gone to! I hope you had a nice vacation.
You really nailed Zach's situation when you compared him to a wishbone. I can see where he would be that way, though. He's moved into a completely new world, and he's left his old world largely behind. To him, it must seem so irrelevant now. And now that he's linked to Will, the support he used to get from his mother must seem much less relevant. Still, those parental ties can bind, so when the pull, it has an impact. It's unfortunate for Barry that he hasn't figured out the real dynamic there.
