Heyho,
I've played for quite some time and though I didn't get to transfer to a female body (didn't have sex with Darina, if that's the trigger), I had that dialogue with Phaid and Selena about Phaid's "Sister", who gave him the medal and my char had the thought, that I should have had a romance with Phaid, while in female body (love-triangle, something like that).
I saw the trailer of totem where I inhabit a girls body, that's why I know it is possible, but in the actual game, ther was no such scene for me in the route I chose. So I think, there should be alternate dialogue.
Also, in the battle with demons to save the city, it is said that Darina is seen by my side and she retreats; but the image of Natalie in a gunsuit is shown, not Darina.
In the end, I like the game a lot by now, it just feels a little rushed for the details.
Greetings, Jo
