This song is probably about a girl the author/loves .
He knows her vulnerabilities but repects her fora all she is.
Although she tries not to cry or to show herself emotional, he knows her deep inside and for him she's definitely a supergirl...
I also think it's a kind of hommage toall the "supergirls" who try to carry on whatever the circunstances(love pain,,,)
