Sometimes it seems like they act like a character is a main character, but really it just means they have a few lines. It doesn't really mean they are an important character to the storyline.

Quick note that discussion about Digory's heritage in relation to this casting call should go in Digory's Ethnic Background.

Okay. Now you're making a part of me actually want to see this idea... stop it  

I'm sorry!  

I have to say, having Jadis say this to a son/brother/nephew before trading his life for the knowledge of the Deplorable Word could be pretty cinematic...

"Foolish boy. Why do you run from me? I mean you no harm. If you do not stop and listen to me now you will miss some knowledge that would have made you happy all your life."

Plus, Jadis being willing to sacrifice a relative in her quest for knowledge and power would be another link between her choices and those of Uncle Andrew. (Yes, we know she sacrificed lots of relatives when speaking the Deplorable Word, but this is a more direct parallel.)

I also wonder if, when writing the script, Gerwig came to the conclusion that Jadis needed a conversation partner for the third act of the story when she's alone apart from the scene in the garden. I don't know if I agree with that (and to be fair, I'm not a script writer), but I could imagine an adaptation where Jadis sees the ghosts of Charn in her imagination when telling Digory and Polly about what she did, and then one ghost doesn't fade away and continues to haunt her, appearing intermittently throughout the film as a figment of her guilt and a threat of what awaits her in death.

If Boy 1 is an entirely new lead character, I think this is my best case scenario.

There probably going to do some sort of visual when it comes to the destruction of Charn I think Jadus just talks about it, but it seems so visual. I am still annoyed they are doing MN first. It just ruins LWW to know what Jadus is before she kills Aslan. I hope they don't try and make her sympathetic.
