Maybe Will owed a large amount of money to another dealer,and inviting Taylor to his apartment was part of a payback,so an opposing dealer could confront him?
It's not like going to a bank, I'll admit it was a really long time ago on my part but drug dealers don't do credit. I'd say it was more like someone wanted the stuff, and they took it. Dealers don't help each other out, they get rid of anyone who'd cross them.
