S1, E4: Vincent revives a 19 year old boy who was left for dead in a dumpster and rushes him to the E.R., where he remains in a coma. After Evan declares that the boys's x-rays reveal a history of bone fractures, Cat and Tess question the father Zachary Holt (guest star Alex Carter) who worries that his son's ADHD and history of fighting and gambling might have gotten him mixed up with the wrong crowd.
