So let's assume Bea is really dead..
This isn't a Bea is alive or not thread but a thread to imagine how the show goes on without her. Okay so who is the main character? Ferguson? Pamela Rabe is the only actress good enough to carry the show, she's the solid scene-stealer (I am tired of Ferguson just speaking of the actress) and what is the plot? The other character's "adjusting" to Bea's death, new characters introduced. Ferguson's trial for Bea's murder? She should go in protection again or she'd be murdered as soon as she walks in Wentworth again.
But the show still needs a likeable protagonist we can root for... Franky but she's outside so her screentime is limited to be a main character, they'd have to put her back in prison, that way she can be on the show all the time.
So go on. Kiss me. Kill me. Do something.
