Hmmm... Gertie will turn to prostitution if she can't find anything else to do, but that will be the last of the last resorts. I don't think she's that kind of girl. So maybe her and Harmony/that pimp will be running into each other sometime.
And she's sure as hell going to try to buy some alcohol, once she gets the money. Hope Grandma doesn't try to keep her from it, or she might get snooty.
