Theme?
Sister or Friend..Warning "Charlene" of the dangerous path, that she is on. Along with Charlene's Male influence that is pulling her down, in the first place.
Charlene, is written in quotes..For that is referring to whatever Disney/Non Girl, you wish to use for her.
Same goes for her "Sister" or friend. As both her sister/Friend and the Bad Male influence, will all need to be crossover, pretty much.
