In the episode he runs tests on Lois after accidentally drinking Carl's dehydrated snake potion that looked like lemonade. He checks her stomach with an ultrasound, and finds some movement.

He later appears in the end of the episode, returning the arch support to Lois. Flattered by this, she invites him into her house for a sandwich, and he gladly agrees to come in. They then talk about themselves, and their interests/disinterests.

And believes that soon he'll find out that the chin doesn't make the man, and will lose interest in the surgery. But apolgizes to Lois if he stepped out of line by not consulting her about it. Lois however believes that it was a good idea, and tells Dave that he should settle down and have kids. And that he would be really good at it.

In Stuff'll Kill Ya, he makes an appearance near the end of the episode. He joins the Foutleys for dinner, and asks Lois if ginger cut down on having the coffee. He then asks if it's hypocritical for her to tell ginger to lay off the drinks, when she herself has three cups a day. She insists though that the situation isn't the the same since, unlike ginger, she's and adult. Despite her argument, Dave and Carl pass glances at one another. Later, when Carl tells Lois and him about having 48 hours left to live, Dr. Dave shares his concern for Carl, and even checks is health, After Lois tells Dave that she's upset that a teacher would tell a student a lie, like that, and that she'll go to the school tomorrow to face the teacher.
