Yeah, maybe Tejo has told her that she can say no, but when she (Indira) tried to gesture to Kostja to come to her, Tejo grabbed her hand and physically prevented her from waving him in.
That’s when I developed a strong disgust for Tejo (and Jirina for other well know reasons) and eventually for Henry for totally unwelcome groping her (Indira) and trying to grab her crotch at every party, knowing very well in what subservient position she was in and how it made K&I feel miserable. He was acting like a low life, and If he has changed, he has a lot to atone for.
