After the wide-eyed firsts of their freshman year, season two of "grown-ish" follows Zoey and her friends as they enter their second year at CalU with confidence and swagger. Learning from the ups and downs of their first year, they all assume they've got their second year on lock, but quickly realize that they're not as grown as they think.

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.
