If I had to wager a guess, Id say that Pascal is playing a slippery conman known in the script as Rex, whos the only new male character that could really be described as a lead in the sequel. Also, the studio was looking to make a diverse hire for that role, and Pascal fits the bill, as hes Chilean-American. Of course, theres a chance he could be playing an intimidating American businessman, but thats a relatively small role that wouldnt necessarily require a rising star of Pascals caliber.
