Advanced Gay - S3-E6
Continuity mistake: We know from this episode that Pierce's father is alive, but at the beginning of episode 1-7 Pierce's mother is on the other end of the phone and speaks about seeing his father's "ghost," as if his father has passed away. (00:02:00)
Suggested correction: Pierce explains in a later episode that his mother liked to believe that his father was dead.
That's not a proper connection. Her "liking to believe" his father was dead is not her literally thinking he's dead- she just wishes he was dead. So she should know enough to know she couldn't have been seeing his ghost. It's a mistake because they decided to write Pierce's father into the show on a later date.
