this is personal thoughts abt it but honestly I don't think rose would have anything to do with june realizing she's trans. IMO a big thing about rose's psychoanalysis is that its not like, actual therapy or psychology its pop psychology interpretations of freudian psychology. I think much like her failing to predict vriska helltiering she also is probably a bit too wrapped up in her own predictions and conceptions of a "canon" timeline that she wouldn't see june coming either. That's just my reading of the character.

I figure roxy would probably be the most likely to really try and get june to crack her egg of anyone still in candy, but honestly I think the people most likely to succeed at cracking her egg are currently both in meat (vriska and terezi).

That's why I think if she doesn't come to the realization on her own somehow before leaving candy the only way she's gonna figure it out before leaving is some time in the hyperbolic therapy chamber plot point if that's even possible still.

(I think it probably will be possible and we will have helltier june but thats neither here nor there)

I think it was in the thread about beyond canon not getting the vriska fundamentals where someone said something about not being too sure about helltiering being officially a marker of personal growth and comparing it to training arcs in stuff like shonen series but I think the difference between those/normal sburb echeladders and the hell tiers in the plot point is that in those shonen training arcs and with the sburb echeladders (and god tiers) they are usually having the characters perform feats to get physically stronger and more powerful, and narratively tying that to a nebulous "personal growth", whereas no feats of strength or will could make vriska descend the helltiers, she had to learn a lesson and actually internalize it each step of the way, and it was only at the end that she was rewarded with the power. It still remains to be determined if she truly did grow but I think at the moment its writing it off a little too strongly to assume that helltiering/plot point therapy is actually also just another bullshit marker of growth like shonen training arcs or sburb's definition of growing up
