While the show had largely kept its fan base happy with no shocking main character deaths, Peter Krause's Bobby's shocking death in the eighth season was tragic and disappointing. Considering the backlash at Bobby's abrupt death, it is unlikely that 9-1-1 will kill off another of its main characters.Aisha Hinds' skilled paramedic has been an original cast member since Season 1. Since there are no rumours or news about Hinds leaving the show, Hen will likely return to the 118 in 9-1-1 Season 9 soon. The preview for the upcoming episode hints that Athena will come to her friend's rescue and will boldly question Chimney's decision to fire Hen. Sooner or later, Chimney will likely realize that he took a rash decision and Hen will be back with the rest of the squad.9-1-1 Season 9 releases weekly episodes every Thursday on ABC.For the latest scoops on your favorite TV shows and movies, follow SoapCentral.
