This scene probably doesn’t mean a whole lot to everyone but the struggle of deciding whether or not to use one or another restroom sticks with trans people. Yes, she’s struggling with which alien bathroom to use, it’s heavily hinted trans symbolism as well. At some point in time every trans person will consider which one they should use. While this is an alien bathroom the symbolism still sticks, especially after season 1 depicting Pidge as a trans girl through the words she uses. It’s all subtext, yes, it’s not “canon,” no, but I see Pidge as a trans girl new into her identity, surrounded by loving and caring friends who support her. Pidge is important and could really help normalize transness, there’s other characters with the same kinda symbolism that can help normalize transness, it’s whether or not that the writers want to give us canon proof or not.
