Alonso is a chem dealer operating via the parking lot of the Monte Carlo Suites. He's a show-off-ish kind of a salesman who always speak in third person and refer to his customer as his "friend." He stays as a minor character which come as quickly as he'd eventually go because it wouldn't be that difficult to tell that he's as shallow as his pitch. You come to Alonso for the chems, not the conversation.
