This episode was very good in terms of examining "do the ends justify the means" and in the end, one guy dies, many others will live (because the ER is fully staffed, no cutbacks) because Carrie sacrificed her medical intregrity for what she thought was the greater good; and Carrie's sense of honor and guilt will eat at her internally for the foreseeable future, and a politician will be ducking for cover, while also using that sense of guilt to hide his complicity in the matter. And the other incredible development out of Carrie's internal betrayal of her medical ethics is her frikkin' promotion as chief of staff! Talk about life's irony. Susan's smart, and will figure it out. Whether she forces Carrie to come clean will remain to be seen. Luka's subplot gives a little more insight inside his trouble psyche. He's still empty inside, competent on the outside, which makes him a desirable commodity at the ER, but besides his job, he has nothing to live for (it seems). Luka has no rudder at this point in his life. The first clue to the Luka confession/introspection is the female voice during their "session". I knew right off that Luka was in the company of a lady of the night (otherwise, it'd be the male pshrink who was badgering him earlier in the episode). Abby and Carter's subplot is just stringing us along for the eventually engagement, most likely during sweeps in May (they suckered us in during the February sweeps with the almost engagement). But I did like their segment at the end. Both of them are becoming more intertwined with the other, and I think some form of intimacy on an id level is developing as Carter sees that Abby now wants to help herself (he was never really able to help her with her inner demons because she simply wasn't "there" yet to want to help herself). Deb cleans up well. Also, they set the table for Gallant's return as an ER doc for future seasons.
