I think that one of the real heroes in One For The Murphys is  Mrs. Murphy.

I think this because Mrs. Murphy saved Carley from her having to deal with possibly abusive foster parents or even going back to her step dad and may have saved her life. Mrs Murphy is also a hero because she took control of the situation when Michael Eric had the seizure.

Another hero is Carley’s mom for the most part. This might be because she stuck out for Carley most of the time. She also treated Carley like a friend instead of an unwanted child.
