Why was Billy Barton reluctant to help the FBI at first?

What was Colonel Barton's secret formula and why did the Order want it?

Q6

Why did Billy's gang team up with the Junior G-Men?

Their collaboration brought together informal detective skills with organized investigative methods to effectively pursue the saboteurs.

Foreshadowing: The serial establishes Billy's gang as having valuable local connections and survival skills that complement formal law enforcement approaches.
