Major Plot hole: Cross, the actual father of the protagonist Weasley Gibson, reveals his true identity moments before he dies in his son arms. However, he had numerous occasions to tell him before that. For years, he was living just besides his son in an adjacent apartment. He didn’t have to try to reach him at a grocery store. He simply had to knock on his door or give him a call.
Unaddressed Issue: The Fraternity receives orders to kill from the loom of fate. An actual loom that gives away names through binary code.

What happens if someone does not live in New York city where all the killings take place?
