After seeing their bus vandalized with a homo/transphobic sign, the next scene has Mitzi in the most fabulous outfit yet traveling proudly, sign and all, through the desert, even more awesome since the actors improvised it, it wasn't originally in the script.
Followed a little later by Mitzi painting over the slur (and the rest of the bus) in a bright pink.
