The Queen, believing duty is all, feels that must automatically make her right, which it doesn’t. The Queen does acknowledge she needs L’Evallier as a kind of conscience which is to her credit but she has the ability of her ancestor, Gwendolyn, to aggravate everyone. The Queen desperately needs to learn to be more humble. Sadly her brief overthrow did not bring about that positive change. It made the Queen paranoid about keeping her family with her, which was not good news for Eileen or Jenny.
Eileen can mishandle relationships. Tact is a foreign language to her. She’s happy to deceive Derek about who and what she is (though she feels she’s protecting him) but would be the first to complain if someone did that to her. Hypocrisy isn’t a problem for Eileen (which helps make her fun to write for!).
She likes freedom of choice but is stunned when Jennifer marries Paul. Eileen does not take this graciously. She snipes at Paul. This looks suspiciously like sulking her daughter did not listen to her! Eileen likes to run the world her way, any world come to that. She has more in common with the Queen than she cares to admit and even more with the Witch!
Both the Queen and Eileen can blunder their way through situations. Best thing to do? Don't get in the way!
