Taken in context with the whole story of the album, Little Girl seems to be the negative forces (think the perspective of Peacemaker) trying to talk Gloria back into being on their side rather than continuing life rebelling against them (lyric: There is no place like home). It also sounds like Gloria was actually a part of "them" before she turned away (lyric: So unholy/Sister of Grace).

Overall, a really good song!
