From vol. 3 of Strangers In Paradise. Katchoo has gone missing, again, and Francine, desperate to know what’s going on, fetches Katchoo’s FBI file. Volume 2 is where SiP stops being just a straight love story (though there’s hints of what’s to come in the initial three issue mini-series) and in the third volume the story of Katchoo’s past kicks into overdrive as it bleeds (quite literally) into the life she’s made for herself with Francine.
When Katchoo dropped out of high school she said she was going to Columbus to live with an aunt. She really wound up in LA, homeless, starving and an alcoholic. She was taken in and cleaned up by a woman named Emma and became, for a time, a high-rent call girl. One of her clients was a woman named Darcy Parker, a power-behind-the-throne business woman with connections to international crime families and a fleet of highly-trained, specially-groomed women known as ‘Parker Girls’ whose sole job is to work their way into the lives and bedrooms of the rich and powerful. Anyway, during this time Katchoo went by the name of Baby June (seeing as she was underage) and the photos in her file - the file Francine is seeing for the first time - show her with Emma and a senator. We never see what the photos actually are and though her particular area of expertise is alluded to more than once we never find out what, exactly, made Baby June so special. All we ever see, really, is Francine’s reaction and I’d say that’s more than enough.
