While ive heard Mikey was one of the reservation as far as his family goes we know now that Joey Chang being underboss was a move by the changs/merlino to have the real power but Joey c kinda did his own thing once he had power and that led to what went down. Natale and Horsehead werent tight enough to know what was really going on no one who was ever ratted that's y they still got the power today.
