Although a part of James wants to argue this point, there's only so far he can defend himself without throwing Francis under the bus--or perhaps the ship, in this case--and he's unwilling to do that. But that doesn't mean he can't hit back in another way.

"Seems a waste of time and effort. We didn't need the supplies you stole, nor did we need you or the men you convinced to follow you. The only losses of note were the men you took forcibly." And so not really part of the mutiny at all. He continues to look forward, as they walk, not bothering to spare a glance backward as he adds a last comment. "Besides, as I hear it you made no better a leader then we did."

Thankfully, they're nearly to the end of the tunnel now.
