Bobby Buell is one of the members on Brock Lovett's
search crew on the Keldysh. He plays a very small role in the film, only appearing in a few scenes. He showed Brock the picture they found under the ocean of Rose and then gave Brock the call when she informed them the woman in the photo was her. Throughout the movie he was mainly seen listening to Rose's stories. In the alternative ending, he watched in shock as Rose tossed the Heart of the Ocean necklace overboard.
