It really made me and some other wonder as we did not see Carter for so many episodes, that what has he been doing - now we see it all from the moment Luka left and what has happened with little mixes from the present Christmas on ER - unique Christmas episode, also.
I adore those Congo episodes - I just cannot tell why, but they are really great. The emotion, the eye-opening different view and story - maybe that shock therapy to show us that there is much more than we see around us every day. Not everyone are so lucky as we.
I loved that Christmas present idea there and storyline with Celine and her family - a really moving on. And Kem - that character as something - not plain, not black and white, with hard and difficulty to understand. I really started to like her.
