They had a flashback to when the kids were younger, and the final scene of Eddie tuning out the family’s music while he listened to rap was a callback to one of the show’s early themes.

ABC renews Fresh Off the Boat, The Rookie, Bless This Mess, Single Parents and American Housewife (https://www.thewrap.com/fresh-off-the-boat-bless-this-mess-among-5-shows-renewed-at-abc/)

Groundbreaking Asian-American comedy Fresh Off the Boat will return for Season 6 after hitting the 100th-episode milestone this season. ABC has also renewed freshmen series The Rookie, Bless This Mess and Single Parents for Season 2. Meanwhile, American Housewife will be back for Season 4. UPDATE: Constance Wu, who has become in-demand thanks to Crazy Rich Asians, seemed to be unhappy with the renewal news (https://www.hollywoodreporter.com/live-feed/constance-wu-tweets-fresh-boat-renewal-dislike-1209752): "So upset right now (https://www.reddit.com/r/television/comments/bn4o3n/constance_wu_rage_tweets_in_response_to_fresh_off/) that I'm literally crying. Ugh. F*ck." she wrote, followed by "F*cking hell." She later tweeted: "That was not a rampage, it was just how I normally talk. I say f*ck a lot. I love the word. Y’all are making a lot of assumptions about what I was saying. And no, it’s not what it’s about. No it’s not..what this is all about. Stop assuming."

I felt the same...but I had the same feeling the year before. I'm glad the show is returning.
