just kinda seems like bargaining tbh
i don't think that meat john could even reasonably stay male in the company of rose and terezi if they knew about june. which y'know, having an alt self in the first place goes against all known metaphysical laws regarding john but we'll indulge a hypothetical here. you get three choices for company here.
you have rose, who can now synthesize dave's habit of calling people gay into her own passive aggressive tactic of giving people diagnoses. there's a joke that could be made involving a certain discredited term but i'll exercise discretion here
you have terezi, whose preferred method of john interaction involves playground insults
and then there's the guy who can reasonably be described as the Bro eidolon
