Bert is a cameraman.
Someday, when Bert finds a gallery that understands his abstract motion-blur photography, he'll be recognized as the true artist he really is. In the meantime though, it's his job as paparazzo that pays the bills. And yes paparazzo is the singular use for paparazzi, and yes it means oversize mosquito in Italian.
It is assumed that he is friends with Hooman.
According to Car Finder, Bert is a Ducham Futuro.
