That morning,
Detective Zack at that time was busy here and there managing something since last night. At first he is on standby if Victor asks him to join in to find Irene and Laura but at the last minute Victor asks him to do other things. To speed up the process of Rosa's case.
Looks like in silence, Victor is the one who help him to make things easier. And just now, he got a news from his lawyer saying that everything looks smooth and Bennet can be detained anytime to help with the investigation as long as the prosecutor is quick to issue an arrest warrant.
Now, he just needs to wait for it. He was already looking forward to giving Bennet a second gift. Last night, he knows Victor already give him a shocked, and it's a shame if they didn't continue the flow.
