Why hello Cutie pie!

Huey and Riley just found out that they have a sister. Hey name is Emily(I know she got a white girl name) But her friends call her Emmy or E. Emily knew she had brothers but never brought it up.She is a really nice girl and doesn't talk alot. So, she isn't a trouble child like Riley but knows her ways around the streets. She is intelligent like Huey, but doesn't complain about others stupidity. What if they fall in love with her?
