Alex's sidekick
From Rom Com
Alex's sidekick (see Kati's sidekick for similarities) is a minor character who snaps cell-phone pictures of people Alex has seduced. He is presumably male but has not been cast yet. In the bet between Alex and Kati, whoever takes the most pictures of people in compromising, presumably seduced positions, wins.
Alex's sidekick appears in Photo Montage and probably The Party, and maybe other group scenes if there are any.
