Quick recap
Gru and Lucy let Balthazar Bratt, a 1980s child star turned villain, get away and are fired from the Anti-Villain League. Since Gru won't go back to crime, most of the Minions leave and end up in jail. Then an invitation arrives: Gru has a twin brother, Dru, who lives in wealthy Freedonia. Dru reveals their father was the Bald Terror, a villain, and wants Gru to teach him the trade. Gru agrees to steal Bratt's diamond but plans to hand it to the League. The brothers fall out. Bratt kidnaps the girls and attacks Hollywood with a giant robot. Gru and Dru team up, shut the robot down and beat Bratt. The girls call Lucy mom, and Dru flies off with the Minions to be a villain.
