I was joking about Thaisha's metal spine being a sort of fantasy scoliosis representation (for those unaware the corrective surgery for scoliosis involves the insertion of rods and screws into your back to hold the manually straightened spine in place) but...
I am now remembering that her PC Decima from when she guest starred on Bards of New York also had various magical metal prosthetics (that heated up!), and that Aabria mentioned in the Study Hall interview that she irl had multiple sports related injuries including a disc to the back that was the final end of her sports career.
So, I do wonder if the plates do speak to some chronic disability management or the magical intervention into some sort of serious injury that we might learn more about now that Thaisha is traveling alone.
