I’ve not read the books but
- Why did Cersei want Margaery to marry Tommen? She didn’t seem to want her to marry Joffrey so seems odd.
- Olenna said her future had been stolen from her when her son, granddaughter and grandson died, but she had other girls around her that referred to her as “nanna”. So did she have more children? Then surely the Tyrell name isn’t dead?
- Why did Cersei want to keep the throne? I never got the impression from the show she was that bothered about being queen.
