Finding Carter had one hell of a drop in ratings. They got from 1 million viewers to 0.3 million viewers. That's a 70% drop. The series might get cancelled. But MTV might renew the tv show for a short last season.
Max (Alex Saxon) will probably be in jail for at least 5 episodes. Crash (Caleb Ruminer) will probably stay to get his buddy out of jail and keep Carter (Kathryn Prescott) company. While a rift between Carter and Taylor (Anna Jacoby-Heron) be the head point of the season. Ben (Ben Winchell) might not even survive the season.
If the season gets renewed MTV might get some guest appearances from Tyler Posey (Teen Wolf), Austin Butler (Shannara Chronicles), Holland Roden (Teen Wolf), Gregg Sulkin (Faking It), etc to the show to get the ratings back up. Finding Carter was 1 of all the shows that really competed with Teen Wolf, now MTV hopes that Shannara Chronicles will do the same and Finding Carter gets back up. But we don't know if the show will be renewed.
Cordin Bleu who will play a part in The Fosters might also get on Finding Carter if it gets renewed to play the role of ... A young man that shares his cell with Max in jail.
