Prior to the character's untimely demise and Rory Cochrane's departure from CSI: Miami at the start of season 3, "Speed" is distinguished in his occasional carelessness in procedure. Especially featured is his neglect of proper sidearm maintenance, which the scriptwriters exploited when they wrote him out of the series. He also at one point borrows Calleigh Duquesne's crime light and forgets to recharge it, much to her annoyace. Speedle's cavalier attitude also features in other ways, as well. He rides a motorcycle, and claims that he's happy with that, rather than a standard automobile.

Also showcased in the series is his role as "best-friend" to Adam Rodriguez's Eric Delko. Ironically, this facet of him is particularly evident in episode 604, "Bang, Bang, Your Debt," a full three years after Speedle's death. Delko, still feeling the effects of a head injury suffered in "Man Down", suffers from vivid hallucinations of his deceased friend, which ultimately leads to the discovery that Audio-Visual Lab Technician Dan Cooper had stolen Speedle's credit cards. This episode, especially with Speedle's appearance therein, illustrates the ongoing trauma of the violent death of a friend (in this case, Speed) on those who were close with that individual. When Cooper claims that, since Speed is dead, no one got hurt, Calleigh Duquesne angrily points out that Eric is hurt, in particular, by the false hope the card charges (coupled with Delko's hallucinations) engendered.
