Oscar was familiar with reading the report letter from the meeting, or the company's financial report last month.
So when he saw the brown envelope, he initially felt normal before Dani opened his mouth. But when he found out that the contents of the brown envelope were the result of a DNA test he did a few weeks ago, he felt like he wanted to stop time.
The past two weeks have been the busiest week Oscar and Dani have ever had. They became uninvited guests at Peter's house for a few days.
After contacting Bryan and asking the man for help, Oscar and Dani started their mission. If they suddenly asked for Peter and Greta's blood samples, the husband and wife would be suspicious and think Oscar would do something crazy. Therefore, Oscar ordered Dani to secretly take Greta's hair which had fallen out or might have stuck in the woman's hair comb. As for Peter, Dani had to take a sample of the man's saliva.
