s01e10 Is There a Doctor in the House?

Delia and her grandmother (guest star Doris Belack) throw a festive birthday party for a grumpy Edna who hates this particular day of the year, but everyone winds up snowed in for the night when a big storm hits town. In the midst of it all, Bright collapses from a burst appendix and Drs. Brown and Abbott have to improvise an operating room before the infection spreads... while Andy and Ephram let months of tension and hurt feelings explode in front of everyone with a threat of Ephram moving back to New York with his grandparents.
