Alexander came to the office attached to his that same night that Hunter talked to Adrian.
There was only Susan, in there.
A few others came to be under him but they all are people who knew what happened to those who came before them. They knew where they should stand that no other problems have occur since the other four were fired.
Susan was also getting along well with them, she became both a senior and a teacher to them. Especially since Alexander only tells them the necessary information while letting them learn on their own. It was Susan who would help them understand things better.
She is also already on her last year of studies and will soon start her residency. As for this matter, those around her no longer found the matter to be too serious as she had been doing so from the moment she came in.
She came in as a student and was accepted due to her knowledge as a scientist.
