But your conclusion isn't entirely fact based either. Waiting for the other crew member to leave may be a lot more sensible that attempting to subdue them. I guess the captain would be able to find any number of tasks to direct the first officer out of the flight deck, but not the other way around.
And working up the chain of assumptions I realise crew hijack is a strong contender, but not a fact.
