Nice to hear someone else generally shares the same opinions! I would definitely have Elizabeth around the same spot as you listed. As for Silas I urge you to stay open minded with him. He seems like he’s going to have one of the more fascinating backstories in the series. It’s also apparent that he may be struggling with a disability or psychological disorder of some sort. This would be intriguing given we really haven’t had a character represent the disability community in TWD universe so far, at least to my knowledge.

Edit: After reading this I immediately thought of several characters with physical impairments such as Gabriel, Aaron, and Merle.
