I agree with everything you said. Sending Elizabeth on the scene even though she's pregnant - plain stupid.
And oh, it was this episode where Luka had those flahbacks? For some reason I didn't even remember that even though I watched the episode like a month ago... Actually I think it was two months ago, but whatever. But yeah, oh, that was SO sad, definitely one of the saddest things ever in ER.
Poor Luka!!
Like you said, he watched his whole family die, it doesn't get worse than that. Like the Bishop said, he couldn't sacrifice one over another. He might had been able to save one of them, but just couldn't leave the other. Man...
And what you said about the accident scene - so true. It was amazing!
