Dr. Ken

Ken is stressed out at work over his “whining, complaining” patients so he needs a therapy session with Allison. Back at home, Ken is nervous about Molly’s driving test – “What if she doesn’t fail!”

When the office celebrates a promotion for Clark, Ken is oblivious since he lives in his own world…it’s the last straw for Clark dealing with Ken’s selfish ways. Clark writes a fake complaint comment card about Ken, so he’s forced to attend a training seminar for better bedside manners, which leaves Allison at home to have dinner with Ken’s parents.

Pat wants everyone to start working on Saturdays, so the workers in the office ask Ken to talk Pat out of it. When Ken visits Pat at home, he's shocked to find out he's living in a boat in the driveway. After Pat explains he's going through a divorce but still loves his wife, Ken thinks they've had a bonding moment. Meanwhile, Dave is given a new nickname at school and it brings up bad memories for Allison.

Ken is taken aback when he meets Allison’s former boyfriend Kevin O’Connell, now a very hot and successful doctor. So when Ken is asked to speak at a banquet honoring Kevin, he uses the opportunity more as a roast. Meanwhile, Molly struggles with a school assignment asking for what she wants to be when she grows up.

The episode opens with a flashback to Ken's botched marriage proposal on Halloween. Now 20 years later, Ken tries to arrange the perfect re-proposal for Allison. Meanwhile at the office, which is decorated for Halloween, Damona and Julie accidentally drug Pat and then take advantage of their boss' suddenly giving mood.

Molly admits to taking a sip of beer at a party, but insists she hated it and didn't drink the rest. While Allison is happy Molly is being honest with them, Ken is afraid of losing his little girl and uses the opportunity to explain to her what alcohol does to the body... in medical terms. His experiment goes awry when he accidentally gets blitzed and makes a fool of himself in front of her friends.

When a job opportunity opens up at Welltopia, Pat thinks Allison would be perfect for it, but Ken isn’t so sure he wants to work so closely with his wife. Molly is stunned with her low SAT scores, and Dave has some ideas as to how to hide the results from their parents. Clark asks Damona’s help in trying to find out what Clark’s boyfriend, Connor, does for a living. Meanwhile, Ken’s father, D.K., makes a surprise announcement.

On Allison’s first work day at Welltopia, she and Ken try to prove the other wrong when it comes to a patient’s diagnosis. After Damona introduces her new boyfriend, Eric, to co-workers, Pat surprises everyone and announces he’s also dating someone. Meanwhile, it’s Dave’s first day of middle school, and he’s nervous he won’t be able to make friends, so he turns to D.K. to help reinvent his image.

When a neighbor girl stands outside the kitchen window staring at Albert, Molly and D.K. try to scare her off. Meanwhile, Ken is surprised when he learns that Pat, instead of him, is asked to emcee this year's annual Welltopia banquet; and Clark and Damona debate relationship styles as it relates to their individual partners.

When D.K. tells Ken he moved into the Park home because he’s gotten a divorce, Ken can’t shake the Korean cultural understanding that divorce equals failure and takes a look at his own marriage. Meanwhile, the divorce news causes Dave to reflect on his relationship with Emily.

On Halloween, Allison is disappointed the holiday doesn’t seem to scare Dave anymore, meaning her little boy is growing up, perhaps too fast. But that might change after D.K. tells a scary Korean gwishin (ghost) story. The Park family, as well as the gang at Welltopia, bring the story to life playing the various gwishins.

Ken is urged to learn Korean when his father's friends poke fun at his inability to speak the language. Meanwhile, Allison helps Molly with her SAT vocabulary prep and Clark is proud to lead the nurses' contract talks, but isn't looking forward to negotiating with Pat.
