It's the rag way.
That bullying, spiteful, bastard tyrant from Govan and his oppressive regime never disappeared. He's almost certainly been manipulating everything that goes on at that festering, disease-ridden cesspit despite having 'retired' years ago.
He never had any intention of stepping down to make way for someone else, he merely stepped aside in order to give the appearance of no longer being in charge. No way would that self-centred, hate-filled tyrant relinquish the power he has over the vermin.
Did anybody seriously think he'd be sitting at home, feet up, carpet slippers on, watching daytime TV when he could still be at the swamp, issuing commands and overseeing everything? Striding up and down the corridors, intimidating and belittling members of staff, just because he can.
The rags built a rod for their own backs with Busby calling the shots long after retirement: history -as is often said- repeats itself.
In this case, good.
