Looking at the female guest on the show, Luke simply asked Alfred, "Which hospital is her daughter in?"
Alfred: "Queens Hospital Center."
Luke nodded and headed to the hospital.
As a detective, he didn't draw attention when he moved around New York. Flashing his badge and asking questions were part of the standard procedure.
If it were a superhero instead, someone might look into their reason for asking questions, and pick out some clues.
Now that Luke was working cases daily, it was very common for him to gather intelligence as a New York detective.
Luke was like a drop in the ocean that was the detectives in New York doing the same thing.
That was also the reason he was reluctant to give up this detective job.
He could openly carry out investigations in New York, the center of the Marvel universe, without attracting anyone's attention, and obtain a lot of internal intelligence via NYPD. Was there any better identity than this?
