Panel 1: (Desmond is smiling, holding a cardboard box, looking at Cedric, who is curiously standing next to an open cardboard box holding straps on a TTY machine)
Cedric: “DAD, WHY ARE THERE STRAPS DUCT TAPED TO THIS TTY?”

Panel 2: (Desmond is smiling with his eyes closed, holding the TTY up, backwards, showing straps duct-taped on it. He is signing invention-kid)
Desmond: “OH, THAT WAS AN INVENTION I CAME UP WITH WHEN I WAS A KID.”

Panel 3: (Cedric is confused, frowning and signing what-that. Desmond is smiling with his eyes closed, wearing the TTY on his back and the straps over his shoulders. He is signing first-mobile)
Cedric: “SO… WHAT IS IT?”
Desmond: “THE FIRST EVER MOBILE DEVICE FOR THE DEAF!”
