Well, I guess this new casting explains why Gracyn Shinyei (young Kate) and Ava Sleeth (young Beth) were on set filming together again. Most likely for flashbacks.
I thought I would be pleased. But to bring Kate back now, only to deny her the Batwoman mantle, is really just more insults by the writers towards her character. Because they already made their choice to replace her with the OC.
I don’t know why they hate her so much.
