As the Fall TV season draws closer, more and more casting changes are coming to light that will surely shake up your favorite returning shows. Luckily, TVLine offers a supremely handy, alphabetical guide to each and every move!

In the month of July alone, we received confirmation that a Walking Dead fave will be walking away from the show, and learned that while a Chicago Med doc is going, he’s not gone just yet. TVLine also broke the news that The Rookie will be in need of a new TO in Season 2.

Other recently announced “Ins & Outs” include The Flash enlisting a former hero to play a villain, This Is Us wishing upon a Once Upon a Time star, a Prison Break vet visiting #OneChicago and Marvel’s Runaways‘ conjuring of a royally sinister sorceress.

In our annual Ins & Outs gallery (click here for direct access), TVLine lists the new series regulars, recurring players and noteworthy guest stars on returning favorites in the fall and beyond, plus a refresher on who has gone bye-bye since last we checked in.
