Meredith (
Ellen Pompeo) and Cristina (
Sandra Oh) open the episode by cryin' the blues over getting romantically involved with their control-freak bosses. Back at Seattle Grace, Meredith's mom Ellis (
Kate Burton), a brilliant surgeon struck down by Alzheimer's, is treated for diverticulitis--which unexpectedly becomes the catalyst for several revelations on the part of several secret lovers. Cristina resists the notion of telling Burke (
Isaiah Washington) that she is pregnant, but this becomes a moot point when she collapses in the surgery room and Addison (
Kate Walsh) is forced to perform an emergency operation. A young female patient (Angela Goethels) who suffers from uncontrollable blushing finds herself in the middle of a few interdepartmental intrigues. And George (
T.R. Knight) is finally able to get the best of the insufferable Alex (
Justin Chambers) when he is handed an unusally difficult assignment. ~ Hal Erickson, All Movie Guide
