Blatant Lies: When asked whether his resignation has anything to do with Stanley Novack's death, Doc Baker denies and makes a half-baked (No Pun Intended) excuse, but it's clear that losing that patient was what greatly affected his self-confidence as a doctor.
Dr. Jerk: Dr. Baker's replacement, Dr. Logan, quickly proves to be the exact opposite of his predecessor; he shows little concern for the pregnant Mrs. Novack (who not only just lost her husband, but also previously had TWO stillborn babies!) and refuses the rooster that elderly Jed Haney offers as payment for his much-needed sciatica pills, but willingly plays along with Harriet's imagined symptoms, knowing that with the Olesons' financial status, he can easily sell her a $1 bottle of his "Female Remedy" (which, as Nels later finds out, is just 90-proof alcohol with flavoring!). Although Harriet later praises the new doctor as "a man of culture and refinement", Nels denounces Dr. Logan as being "a bit uppity" for his taste, and reminds his wife that "good manners don't necessarily make good medicine".
I Let Gwen Stacy Die: Doc Baker's reaction when a patient under his care dies, even though the man refused further medical treatment until it was too late.
My Greatest Second Chance: While he's initially reluctant to help Stanley Novack's widow deliver her baby, as he already failed to save her husband, succeeding in doing so is implied to not only restore his self-confidence but make up for the loss of Stanley by saving his son.
Tempting Fate: Dr. Baker rationalizes his decision to resign and become a farmer by saying that if it doesn't work for him, "at least I won't harming anyone but myself". Not only is his attempt as a farmer an Epic Fail, but his replacement as local doctor is a neglectful, downright harmful substitute, especially when he's nowhere to be seen at the time widowed Beth Novack goes into labor.
Unsuspectingly Soused: Mrs. Oleson accidentally gets drunk with Dr. Logan's "Female Remedy", which is little more than 90% alcohol with flavoring!
Unusual Euphemism: Mrs. Oleson insists to Dr. Baker that she has the same condition as the heroine from a novel she read, despite Dr. Baker insisting that she's in perfect health. When she repeats what the doctor in the book described as "injurious exhalations from deep within the recesses of the body", namely "the vapors", Dr. Baker can barely keep himself from laughing before recealing that they use a different name for those vapors nowadays: gas! An infuriated Harriet leaves the Dr.'s office ignoring his suggestion to avoid greasy foods and sweets, and Doc Baker bursts in laughing after she's out.
You Are Better Than You Think You Are: With the inhospitable Dr. Logan nowhere to be found as Beth Novack is going into labor, Charles insists that Dr. Baker (who has chosen to quit medicine and take up farming) step up to the plate; as the latter is still visibly shaken because he couldn't save Beth's husband Stanley, Charles gives the good doctor a much-needed pep talk, which supplies the boost he needs to successfully deliver Beth's healthy baby boy. His self-confidence now restored, Dr. Baker tells Charles that he's going to throw Dr. Logan out of his office and return the farming equipment which Charles had previously loaned to him.
