Talk:Sue Ellen's Little Sister/@comment-5389150-20120121183317

I've composed a theory here. Fern was shown to have a sister. Apparently that girl seen with Fern is Mary Ann. There is one problem with that though. Mary Ann's father looks completely different from Fern's father. Not only that Unknown Male Dog apparently is Mary Ann's brother. So if that's also the case then Fern should also have a little brother too on top of a little sister.

Another thing is Brain having a sister. I don't think that girl with Brain is his sister. The girl is 3rd Grade Female Aardvark who is one of the 3rd Grade girls that wears her hair in pigtails. So I can conclude that either the female character is actually Brain's younger sister (keep in mind Brain is suppose to be in the 4th Grade) or that's one of Brain's friends.

Then again we have to take into consideration that we know very little about all the other minor characters that have appeared throughout the last 15 seasons of Arthur. So as for where I stand on both issues I'm neutral.
