Disclaimer: I am not a therapist. I do however have several close friends and family members who are, so what little info I have about this kind of stuff is mostly true, to the extent of my knowledge. I also am in no way trying to judge anyone based on their opinions. Shallan is a fictional character, and everyone is entitled to their own opinion, whether or not I agree with them.
Personally, I really like Shallan, for a few different reasons.
Firstly, one thing I haven’t seen people talk about here is the science behind trauma. When you experience something traumatic, especially something tied to your family or other close relationships, it doesn’t just become a ‘bad memory’. It physically changes other parts of your brain. Your brain actually buries those memories and changes how your body works and responds to stimulus, especially anything related to the trauma. Since you now have heightened and extreme reactions to things similar to that trauma, dealing with it and experiencing it isn’t just like remembering your last birthday party, you have to relive extremely painful events that your brain has trained itself to see as way more painful as it was. You actually make those memories more painful.
Now, considering Shallan, she is interesting because every Ideal she swears means she has to confront one of her many, many traumatic memories, and then she can’t forget it again later, something your brain is designed to do. Her progression through power isn’t about vowing to protect people or realizing you can’t protect everyone, which is growth for Kaladin. Her progression is about forcing her mind to acknowledge things it has literally changed itself in an attempt to forget those memories and protect Shallan from them. Her progression is a much more painful and serious process. And, since she can’t forget it again later, she has to constantly live with those memories, which probably resurface constantly. Knowing this, is it any wonder she created alternate personas to cope with those memories? Seeing this growth and development of having to unbury deep trauma is something I can really relate to and think is really interesting to read.
Secondly, compared to the other characters, Shallan’s struggles are ones that as far as I’m aware are almost completely unique to her as a character. Sure, Kaladin and Dalinar are great and really demonstrate other mental illnesses, but those mental illnesses are fairly common across other fantasy. Very few stories accurately portray a DID main character this well. Most DID is portrayed in the media as a method of making the villain reveal be “the main character the whole time?!?!” or something like that, but Shallan is interesting and unique in that her DID is not a plot device, but instead an obstacle that actually makes it harder to progress forward. That’s a really difficult thing to write, and part of why I like Shallan so much is that BS did this so well.
Thirdly, Shallan’s arc isn’t as action packed as the other characters’. Sure, action is fun, but when we have so many characters full of action packed scenes it is really nice to be able to sit back and have some more interesting things unfold, which is still very, very important to the plot.
The last thing I want to address here is what other people are saying when they say they don’t like Shallan. The main two arguments are 1. She doesn’t do very much to further the plot, and 2. Her jokes aren’t very funny. Now, these are both totally valid reasons to prefer other characters. The second one is mostly opinion, but as someone pointed out they were originally a coping mechanism for her and her siblings during a time of trauma, so even if the jokes are pretty bad I like how they are included and demonstrate how she is growing. The first point I disagree with. I think she has done so much in every book to further the overall plot of the series. Sure, it may not be as much as the other characters, and maybe it doesn’t help the immediate plot, but it is important regardless.
Now, I’m not trying to say I think you are wrong if you don’t like Shallan. Your opinion is totally valid, and I completely understand why you might say that. I really hope this post doesn’t come across as accusatory or judgemental, because that’s really not my intent. All I want to do is share my reasonings for enjoying Shallan and hope that I may help you guys to see a different perspective, even if you don’t share it.
Thanks for listening to my rant!
