Laybecker accepted the card, and wasn't surprised that it only had a name and a phone number on it.
Luke had left a deep impression on him.
Not everybody could knock out two armed criminals with frying pans.
In doing so, Luke had saved Nash and rescued Laybecker from the freezer. Laybecker had to remember this favor.
If nobody had let him out, he probably would've frozen in the freezer.
He could go on a rampage tonight and finally blow up the submarine that the Tomahawks with nuclear warheads were going to be loaded onto, all thanks to this young man.
Nodding and accepting Luke's gesture, he left with the group of SEALs.
After Laybecker left, Flegg asked Luke, "Why are you here?"
He knew everything about Luke, including certain information that was confidential.
Logically speaking, Luke shouldn't be here as a LAPD detective.
Luke nodded and said, "Personal request."
