S1·E26 A Very Present Help

Glynis Johns plays a nun who gets admitted to Blair because she has gallstones and needs an operation. She gets involved in some of the patient's lives and problems, tries to help and is scolded by Kildare before he apologizes and realizes how good she really is. The episode is too long and deep to explain in words, BUT, it is one of the very best that they ever produced. An A plus for this show.
