I like to think of Starlight and Trixie as friends with benefits. They might have questioned whether they had a crush on each other or not but eventually realized they just liked each other’s company and also liked the steaming hot lesbian sex with occasional mild drug use, but didn’t really want to get married or tell each other sappy love poems or anything like that.
Don’t even give me that. There’s no way a couple of irresponsible tarts like Starlight and Trixie didn’t get into at least the light stuff. Trixie’s smoke bombs are probably a bigger health risk anyway.
By the way, there is a real plant here on Earth called “horseweed”. Several, in fact, and they are all horribly toxic to actual horses.
