In later seasons, the character has matured and in Season 8, Ryan is shown to be taking on more leadership responsibilities (e.g. directing investigations, interrogating suspects alone). He has since been promoted to CSI Level 3 and led investigations in Calleigh's absence. Ryan may have shown some leadership, as in the crossover episode "Bone Voyage", in which Dr. Raymond Langston, played by veteran actor Laurence Fishburne, crosses over Miami and later on before heading back to Las Vegas. Fishburne is the second actor to cross over 3 CSI's after Caruso, who appeared occasionally and separately, on all CSIs. This is also where an actor (Amanda MacDonald, who plays Madeline Briggs) becomes the first female to cross over all 3 CSIs as the same character.
