You were correct first time. Bonin was PF in the RHS throughout. Robert replaced Dubois in the LHS. Robert had been resting (dozing) until not that long before the incident, which may partly explain his initial failure to get on top of the matter (UAS SOPs etc).
So the youngster got a hold of the SS and from then on the FO was reluctant to take it back away from him until the very end? In both scenarios it seems that the FO dropped the ball (no assertion). It doesn't make sense from his shoes. So, he was the one screaming for the Captain to return? And the Captain before leaving said at one point: He (FO) will take my place? If so, that kind of place him in charge, doesn't it?
What an innocent mess?
