I just read this about BRILLIANT MINDS, the series which stars Zachary Quinto and in most episodes (as his character's mother) Donna Murphy. In the most recent episodes, they'd introduced Mandy Patinkin as his character's father.
"Sadly, the ratings and viewership are a significant hurdle to a second season, as declining ratings suggest the audience is losing interest. NBC also has Chicago Med, and may feel it doesn't need a second medical series if people aren't enthusiastic enough to tune in every week. These factors put the freshman medical drama at risk of consisting only of the 13 Brilliant Minds episodes from this season. However, the EP's detailed plans for season 2 suggest he has reason for optimism regardless and that the stories begun in the finale will not be left unfinished."
