User blog:D.Ryan/As Sonbird is to Big Daddy as Elizabeth is to Little Sister

Hey guys!!! it's your #1 blog writer here and today, I oticed a little something about Elizabeth and the Songbird and a Little Sister and the Big Daddy

The Same?
Well the Songbird gaurds Elizabeth as a prisioner right?

and a Big Daddy gaurds a Little sister as a protector right?

Is there some similarity between these two relationships?
