They thought that everything will go according to their plan but Stefan was one step ahead of them. To make sure that his family will be safe, he told Dominic to stop his part-time job for a while. He also communicated with his work place since he owned it as well. Of course, the management didn't make things difficult. Even if Dominic got in through the back door, they couldn't deny the fact that he was very efficient and was very diligent with his work as well.
As for Luiz, since his work was mostly outdoor, Stefan negotiated for Luiz, telling the photography team to do the work in one of his properties. No matter what kind of set up it would be, Stefan would compromise for the sake of their safety.
