Lewis is a friend of Brock Lovett. A redhaired, bearded, overweight technician, he wore a black t-shirt with a smiley face shot on the head. He seemed to be a Titanic buff and the "geek" of the team on board the Akademik Mstislav Keldysh. He operates the Keldysh ROVs and guided Snoop Dog into the wreck of the RMS Titanic, controlling it to uncover Caledon Hockley's safe.

He often swears and does not mind insulting or discouraging Lovett in friendly terms. After their failure to find the Heart of the Ocean in the safe, Bodine reminded him of Geraldo's ruined career in an attempt to warn his friend.

While Rose DeWitt Bukater was on her way to the Keldysh he recited to him all his research on "Rose Dawson's" life, claiming insistingly that she was dead, and Rose Calvert was only a fraud seeking publicity, comparing her to the case of Grand Duchess Anastasia Nikolaevna.

Lewis demostrated to Rose a 3D animation-simulation of the Titanic sinking, mimicking the sounds of the disaster with his mouth, concluding that it was "cool".

He later found funny that Rose wanted to jump off the Titanic, laughingly adding that she could as well wait for only two days.
