With more patients dying, Edwards offers to share a procedure he learned in France, but is rebuffed by Thackery and Gallinger.

Thackery weighs performing surgery on a former flame, and orders Gallinger and Chickering to experiment on pigs. Barrow goes the extra yard to square a debt. After a bad day at work, Edwards takes out his frustrations at a local bar. Robertson is relieved when her pleas about treating a patient with typhoid fever are finally heard.

During surgery, Thackery's hand is forced by Algernon, which irks Gallinger. A recovering Abigail regrets her involvement with Thackery and Sister Harriet and Cleary make a couple of deals. Meanwhile, Bertie receives a scolding from his physician father who is unhappy with his son's career path and Lucy becomes privy to Thackery's secrets.
