Character Analysis
To tell the truth, it's kind of hard to come up with too much to say about Pablo. Whereas the other friends all have characteristics that are easy to identify, Pablo is sort of the featureless friend who just goes along with everybody else's plans. He's always there, ready to help, but he doesn't come up with any ideas or plans on his own.
For example, when Pilon starts to talk himself out of paying Danny the rent he owes, Pablo is willing to support him in that endeavor, but he doesn't really add too much to the conversation:
"It is just as well that we do not take two gallons of wine to Danny," said Pilon. "He is a man who knows little restraint in drinking."
Pablo agreed. "Danny looks healthy," he said, "but it is just such people that you hear of dying every day." (5.4-5)
It might seem like Pablo doesn't have all that much to do in the novel, but every Michael Scott needs his Dwight Schrute, and Pablo is just that for Pilon: his ever-supportive yes-man. The scenes with Pilon would be way less funny if Pablo weren't there to throw the ridiculousness into relief.
