As was announced over the summer, fresh from the Broadway smash “Hamilton” – for which he won a Tony Award playing Thomas Jefferson and the Marquis de Lafayette – co-star Daveed Diggs booked a season 3 arc as Rainbow Johnson’s brother, Johan, for the third season of “Black-ish,” as the Johnson family  expands.

Bow (Tracee Ellis Ross) and Johan, whose mother is a very laid-back, hippie-ish soul, had very different childhoods than Dre, and that’s partly why Johan will be a frequent thorn in Dre’s side. Dre Johnson (Anthony Anderson) has always feared that his kids will grow up to be overly pampered, and it sounds like Johan is the personification of those fears.

“He’s sort of a hipster, entitled kid who gets on Dre’s nerves,” creator and showrunner Kenya Barris said in a previous press statement. “He’s constantly on a search for the best conditioner for his hair. He’s probably gone to Penn or Wharton and could have gotten a great-paying job, but he’s trying to find himself. That attitude more than anything makes Dre want to strangle him.”

The role will have a “substantial” recurring arc, said added Barris.

Diggs makes his debut on tonight’s episode of “Black-ish” which airs at 9:30 p.m. on ABC. Ahead of tonight’s broadcast, ABC has released a clip from the it, featuring Diggs, which is embedded below:
