And there are many I’d love to write for, too! I love so many of them. I think, even though those three are amazingly different, they are all such well-fleshed out characters. I would argue that Mike had the most character development in the pre-2005 series than any other character. He was complex and did the wrong thing for misguided reasons – like we all do from time to time. Generally, companions are human and they need to display human emotion and vulnerability and empathy.
