Your RQ (or anyone else, for that matter) does not have the
power to extend your ORD.
Unless if you do something really naughty and get yourself
thrown into DB.... which I doubt is the case, yes?
The only thing I can say is to hammer it into your understudy's
skull that he has to learn now, because after you ORD, he's on his
own. And warn him that you will not bother picking up the phone to
help him how to do his work after you ORD.
And seriously, don't bother any more about him after you
ORD.
You might also want to confide in your RQ about this fella. Your
RQ might want to drag this fella into his office to give him a Sir
Alex Ferguson 'hair-dryer' session to wake up his ideas.
