Youtuber argues that Mabel should have been called out
A youtuber that I watch on occasion named "pieguyrulz" made an interesting argument that people rarely seem to bring up. He says that Mabel should have been called out on her deal with Bill Cipher, even if she didn't know Blendin was Bill in disguise. Then he gives some interesting points as to why he feels that way. A link to the ten minute video is below.
