Don't Push - S6-E2
Continuity mistake: While trying to take a new Family Portrait, after Cameron, Mitchell, and Lily shake out their faces, say cheese and take another photo, Cameron goes to look at the laptop screen and there's a closeup of that newest photo, but when he tells Mitchell to look at the screen it's a different photo - note Lily's goofy eyes, etc.
Continuity mistake: Pepper states in this episode that he doesn't have any kids, but in 4-14 "A Slight at the Opera" he talks about a son he has who is a Navy Seal.
Continuity mistake: Whilst Clare and her new 'best friend' are talking to the flight attendant, the two glasses change from empty to full in the next shot.
Continuity mistake: When Alex opens the door for Sanjay she is wearing red headphones around her neck, in the shot after that the headphones are gone. Two shots later, they reapear. (00:11:10)
Answer: Mitch is upset that his dad doesn't seem to support his getting married. When they talk about Jay's friends not coming to the wedding, Jay makes it seem like Mitch wouldn't want them to come anyways. Mitch sees it as it's actually that Jay doesn't want to invite his friends to his gay son's wedding because he's embarrassed and uncomfortable about having a gay son. Essentially Mitch sees it as if he was marrying a woman, Jay would be willing so spend money on the wedding, host it at the club, and invite all his friends to it.
