Douglas is divorced three times and has been kicked out of Air England...there are quite a lot of situations where having many tricks up his sleeve did NOT help him.
And in fact apart from St. Petersburg most of the troubles he solved over the series where things that would not have had major consequences if it hadn't worked.
I'm not saying that the end of MJN would turn him in an emo-woobie but it wouldn't be easy for him either...
