Technically, anything related tois a spoiler for the TV show, even her name, as it was not mentioned in the TV show yet. She is nothing but a vague hooded figure (with a apparent 10 foot sword) to people who have chose not to read the comic. She will likely get a lot of play in S3 trailers though, so bits and pieces of random info will not harm most peopleMichonne
Alright, I tagged the bit that I mentioned about her "pets" earlier, but I still don't think that was a spoiler. Plus its already been put "out there" in this thread by others, but whatevs. Better safe than sorry.
