Cassidy Bullock was a young man who had light brown and blue eyes. He did not wear an employee's uniform when working. Archie was able to catch up to Cassidy during a chase, meaning that Cassidy may not have been able to run very fast.
Upon meeting Cassidy, Veronica seemed to think he was a pleasant person, as the two began to flirt soon after their first encounter with each other. However, sometime later, Veronica was able to suspect that Cassidy was not who he seemed to be, and instead, was a thief interested only in valuables. He is also intensely resentful towards those of upper class.
