According to Wikipedia... After colleague and friend Eric Delko is critically wounded in the line of duty, Calleigh and fellow CSI Ryan Wolfe go to the hospital to give him blood, but they learn that they are too late and that he is on plasma due to catastrophic blood loss. Calleigh and the others take turns at his bedside; she places a cross in his hand to show how much she cares, and is scared for him while he is unconscious (Eric is Roman Catholic); She is the first to talk to Eric after he wakes up, and the first to learn of his impaired memory when he asks after his months-dead sister Marisol. Calleigh, not wishing to upset Eric in his critical condition by reminding him of her tragic murder, demurs for the time being. She is instrumental in discovering his shooter by her analysis of the bullet fragment recovered from Eric's head. After Delko's return to work, Calleigh keeps a close eye on him, going over his reports and hoping his recovery is as complete as they would like. Unfortunately, she discovers a small but critical error in his procedure, which almost allows a killer to escape justice. Later, a depressed Delko declines to join her in the interview room, saying forlornly he came back to work too soon, even though he earlier provided critical insight to the case. Sympathetic, Calleigh allows him to sit out the interrogation. The impairment of Eric's memory is further demonstrated when he fails to remember the woman who was suing him, and Calleigh intervenes for him. Eric appreciates that, and Calleigh appreciates being appreciated, at which point she surprises him by kissing him on the cheek. After Jake is involved in an accident, Calleigh and Eric share a moment in which she verbally compares the relationship she has with both men, revealing that while she doesn't know how she feels about Jake, she trusts Eric with her life. This comparison seems to please Eric. Later, Calleigh and Jake kiss, with Eric looking on jealously. Calleigh notices that Eric saw the kiss and looks very guilty as she gets on the elevator. In the episode "Smoke Gets in Your CSIs", Eric finally tells Calleigh that he couldn't imagine living his life without her, and in the episode "Sink or Swim", Calleigh and Eric share a kiss after Eric is released from jail for having a fake birth certificate. In the episode "Wolfe in Sheep's Clothing", Eric is seen waking up nude in Calleigh's bed and they share a bathroom as they get ready in the morning. As of Season 7, they are in a romantic relationship they are keeping hidden from the rest of the team.
