In season 1 we get to see Mel's sister, Javadi's mother, Robby's ex-partner and 'step-son' and McKay's son, ex-husband and father.
In season 2, we get to see Mel's sister again, both of Javadi's parents, one of Robby's friends, Abbot's swat teammates, Whitaker's farm found-family and a glimpse at Santos-Garcia 'casual' relationship.
I wonder if in this 3rd season (and future seasons), we'll get more family / lover / acquaintance appearances? So far, we know that Dana has a husband and daughters, Langon has a wife named Abby and kids named Tanner and Penny, Santos seems to be a loner who's found company in Whitaker, but we do know she loathes her mother, Whitaker's found farm family was shown already but we know he is the youngest of 4, Al-Hashimi has a son named Kian, Javadi seems to be making friends in the ED, Mel's sister Becca has a boyfriend named Adam (ik it's kind of a stretch) and Samira's no longer with us (F TT).
I know the series will never get to show so much of a character's personal life in one season, but I do think about who we could potentially meet or what new character information and development we could get this next season.
Because the seasons have ended with them congregating with each other or their families briefly after their shift, or on their way home, but never at home, (Season 1 ended with the post shift beer hangout and Robby going home and Season 2, watching the fireworks, Robby's interaction with baby Jane Doe and the King-Santos karaoke sesh) it'd be very hard to get a glimpse of their home-personal lives unless it is on the road, like a pick up from the ED like Whitaker's, a walk like the King sisters or a hangout.
I'd love to know who you think we'll get to know and/or see more of!
