Connor: (to Miles) When I was about your age, I could figure out any disease they showed me. I was young, invincible, filled with promise… and pride. And then… someone very dear to me came down with a bacterial infection in their lungs, it defied everything the doctors threw at it, so I flew home, I told the doctors "I can fix this.", I had to save this one person… but I couldn't. See, nature doesn't care about how much training we've had or how smart we think we are, nature doesn't give a damn. So my advice to you is this – either learn how to deal with it, or quit… but I think you're too good a doctor to walk away from this.
