Chicago Hope Season 6 Episode 12

A railroad engineer with a drug-resistant strain of TB requires a form of surgery not performed anymore. There is an expert at it, though--- Wilkes' aunt Odelia, a brusque woman estranged from her nephew. Meanwhile, Simon is perplexed by a paranoid woman whose physical symptoms keep changing. The root cause of it, she believes, is God's revenge: she had turned away her dying twin sister.
