ER...who the heck is left?!?

I just finished watching ER this evening. It was Abby's (Maura Tierney) last episode. So far this season, and we're not that far into it, the writers have gotten rid of three main characters - Luka, Abby and Pratt. Who the heck is left for the rest of the season? How interesting can it possibly get? I don't know, but I'm hoping to have more quiet Thursday nights like this so that I can actually watch the original airing of a show!

And yes, it made me cry a little.
