Hol Horse and Boingo, Part 2

Hol Horse and Boingo followed Jotaro and the others to Cairo and as Boingo's book said, Hol Horse stuck his fingers into Polnareff's nose... but he didn't know what to do from there. Then Jotaro and the others, who were looking for Polnareff, show up, but things seem to be going the opposite way of the premonition.
