Back downstairs, Mark treats a woman who seems to be hyperventilating. He orders a bunch of drugs and tests and asks the patient, "Do you take digitalis, dear?" Okay, seriously, what's with the docs calling women much older than themselves "dear"? I don't even like old people to call me dear, so if I were old -- and it's hard to tell how old this patient may be, since she has an oxygen mask covering most of her face, but if she's old enough to have heart problems that require her to take digitalis, she's probably at least in her forties -- and some punk-ass clown like Mark called me "dear," I'd poke him in the eye. Anyway. She seems to shake her head no to the digitalis question, but I guess she must have said she does, because he then asks her whether she took any today, and when. It seems as though she took it this morning, so Mark calls out for someone to "add a dig. level." There are more drug orders, and then, in the brief moment of stillness, Mark glances around and smiles to himself, "I can't give this up." Digitalis looks alarmed, and Mark notices her and quickly assures her that she's fine. Lydia shows up to say that Jen is on the line for him. Mark gets back to work on Digitalis, telling Lydia he'll have to call Jen back.
