I love you, bb, but we try not to bash on the writers, actors, characters, producers, etc., here. Just an FYI. Also, not everyone has seen S4 so we put things like this under a cut. Sorry to be such a buzzkill.

You know that even if she is killed she'll still have a following so I think Frozen Sovereigns is a great name. Besides, she may not be killed and may recur. You never know with this show. Plus, it's Liz Mitchell. She's pretty well known so I think her fans will love her in this part (I know I do) and want to keep such a cool name.
