Galdian,
Nurries mate... Sometimes cultural differences and humour need to be reminded of each other. The "rant" was good to remind us all too.
As to the F/O taking over in such a situation, it is laid out in the manual under the, if I remember correctly, Basic Operating Manual (GA's company manual (equivalent QF's Flight Administration Manual) under, I am told, non-normal and CRM sections).
Has he screwed himself bigtime? Well, we have to wait and see... but with the limited info we have, looks like it...
