I'm trying hard to put these feelings into words, but it's very difficult. They are visceral reactions, not cerebral ones, and that makes them hard to express. I'll keep trying, but no promises.

Assorted comments:

• If you're going to self-destruct and do things that have adverse consequences, that's fine. Just make sure other people don't get caught in the blast radius, particularly when they didn't ask to be there.
• I'm not sure exactly Doug thought he'd accomplish by driving to the accident scene on his own -- access is controlled pretty tightly to those things, and with Mark being the senior medical person present, I doubt he'd not notice Doug slipping into the bus to work on the kids. Up here, the fire captain has final say over who can and cannot enter a given incident scene (when the FD is attending), and disobeying him lands you in jail. (I suppose it's kinda like on Homicide: the control of the primary detective over the crime scene is absolute.)
• Once again, Carol and Doug, you two really need to stop getting so personally involved in your cases. You treat the patient, they go home, that's it -- you don't go home with them. Why? It's simple: it's unprofessional to use friendship or kindness as the basis for a practicioner/patient relationship, and invites all sorts of messy problems -- witness the last few episodes. "Know your limit," I suppose.
• I wonder -- how much does emergency department care cost on the show? We see a lot of patients who seem to spend an inordinant amount of repeat time in the ED; in real life, you want to transfer these people out of the department as quickly as possible for a few reasons. (It's expensive care, and the beds are always in short supply.)
