Niles prepares to undergo heart bypass surgery. He is surprised to receive a call wishing him well from Maris, who had learned of his plight from a gossipy acquaintance. Frasier tries to keep Roz and the family at ease by researching the procedure (as well as the doctors' backgrounds) and printing out detailed descriptions for everyone. However, he winds up getting on the surgeon's nerves by questioning his approach to the operation. Martin tries to act as though everything is fine so that he doesn't have to deal with the fear and uncertainty of the situation. Roz tries to help the terrified Daphne stay calm. She refuses to think of other things, stating that she has no future until she knows that Niles is all right. (thetvdb.com)
