sister comforts brother

Twins Mason and Madilyn haven't even been born yet but a sonogram picture shows the little girl holding the hand of her dying brother.  Doctors have told their parents that Mason probably won't make it and they're at least consoled that his sister is there for him during this time.  Mason has a hole in his heart and some brain damage.  Because of this, doctors can't do surgery to save his life.  They can only wait until it's time to deliver the twins.  Mason and Madilyn
