Names. Not my area.
I think this is a Thirteen thing… and I think this is Twelve’s too. Thirteen is nicer to her friends but she still has a tendency to be blunt and rude but this time the Doctor learned to (or kept the lessons learned as Twelve) direct it to self-important antagonists.
Thirteen effortlessly undermines her antagonists, they’re not important enough for her to retain their names nor make an effort to use their learn their names because they’ve proven themselves to be Grade A jackasses. Thirteen’s responding in kind and makes it look so easy undermining them.
