[[WMG: The Pink Haired Girl's name is Down.]]
Read all the titles of the comics that feature her as the main character. Notice the trend?

[[WMG: Justine is a lesbian.]]

In [[http://www.viruscomix.com/page591.html #224]], Ethel and Pink-Haired Girl use Coke vs Pepsi as a metaphor for sexual orientation. Liking Coke represents attraction to men, while Pepsi represents attraction to women. The woman General Pete talks to is drinking Pepsi and is a lesbian, continuing the metaphor. Justine is also drinking Pepsi.
