Zoey Breaks an Unspoken Rule in New Photos from grown-ish “New Rules”

Promo photos from a brand new episode of grown-ish have been released. The episode is called, “New Rules” and it will air on January 9.

In the episode, “Zoey struggles to make amends after accidentally breaking one of the group’s unspoken social rules and upsetting both Jazz and Luca. After Aaron and Vivek’s kickback is shut down by campus police, they try to find other ways to turn up.”

I wonder what rule Zoey broke? Any thoughts?
