Panel 1: (Helen is concerned, approaching a counter with the words SCUBA DIVING on it. Behind the counter, there is a concerned male employee, pointing at Desmond, who is looking at some swimming flippers in a bin)
Man: “YOUR HUSBAND IS DEAF? I’M NOT SURE THIS WILL WORK.”
Helen: “WHAT DO YOU MEAN?”

Panel 2: (The man is pointing at his ear, speaking to Helen, who looks confused)
Man: “I HAVE TO BE ABLE TO COMMUNICATE WITH HIM UNDERWATER AND HE CAN’T HEAR.”
Helen: “HOW DO YOU COMMUNICATE WITH PEOPLE UNDERWATER WHO CAN HEAR?”

Panel 3: (The man is talking with his eyes closed and making some hand gestures: 1 handshape, time, thumbs-up)
Man: “WELL, WE USE HAND SIGNALS TO… OH WAIT!”

Panel 4: (The man looks embarrassed, blushing, and tugging his shirt collar, holding up a paper and pen. Helen is smugly looking at him)
Man: “DUH! SORRY.”
