Home Cheapo - S9-E7
Continuity mistake: When Carrie finds out that Kelly and Deacon have afforded a lakeside house, she makes reference that Kelly doesn't even work. But in the previous episode ("Brace Yourself"), Kelly has a job. They even need to hire Spence to help out.
Suggested correction: What if she quit the job, her employment was terminated, or it was a temporary/seasonal position?
