Episode #3.6 - S3-E6
Continuity mistake: There's a rather burly woman with short blonde hair and a pink dress in the very last shot of the episode. She is an extra that keeps popping around in the ending scene at different times (before Dwayne's hot tin roof line, and during Catherine's magical angry bird memory). (00:51:35)
Answer: There's probably no particular reason. Sets and props on long-running TV shows often change as needed and for various reasons throughout a series run.
