Why David Mayer is not capable to lead?

When he had accused me for Chrisnna's past life. So as to steal my shine and sum.
Then now he plots for his revenge. Whe. DAVIDis with Sofia of Sp... they are f*cking!
I never want to hear harassment nor ego tripping about me. Because David Mayer was never my ex!
Just using me for any access in the bank. When NAZIs guard the BANK now.
