As for the promo, it teases some memorable moments from the series in the past and an emotional group hug where the entire family has an emotional breakdown.

"I think it's going to be really emotional to watch it on television next week. Now that I don't have anywhere to go, I've been able to sit down and watch the show in real-time, which I haven't been able to do before. So I think it'll be interesting to watch it while all of our fans are watching it for the first time," said star Jesse Tyler Ferguson about the finale in conversation with The Wrap.
