Earlier quoted context omitted.
PG doesn’t say he’s fit for the job, he just says he’s good at some unspecified thing. Maybe that unspecified thing is just corporate knife fighting and this time PG is happy he’s not on the other end of it.
Maybe the situation he’s good at dealing with is… getting fired?
And seeing as he’s going back into the company, it looks like he is better at dealing than most predicted.
