Zoey's romantic life is always front and centre on Grown-ish, but Jazz is a bit more consistent. She's vocal about her feelings for Doug, whether she is in love or is in need of something more.
At the beginning of season two, she and Doug are considered #CoupleGoals over Zoey and Luca, and their natural connection is enviable. There is a huge possibility the two of them reconcile at some point, and an unexpected pregnancy isn't an impossibility. Jazz will have to deal with a lot if she is pregnant, including her sister's reaction to losing her twin to someone — as well as her current track scholarship.
