I watching the Lockdown rerun the other day and I noticed at the end when Carter and Abby are talking, Abby takes an ice pack out to put around Carter's neck and the ice pack keeps disappearing and reappearing. I never noticed it before when I watched that episode :lol:

Another time, Luka gave his patient's age as 16 years old, but later he tells the eye doctor that the patient is only 14.
