This was a pretty good film. I was actually hoping for a little more substance to it, but it was good.
I thought an interesting scene was when Lukas went to Fabio's house unannounced and observed that he lived with his parents, who were aged and ailing. We see Fabio tending to his father before he notices Lukas and rushes him out of the apartment. The scene is important to Fabio's character because we had been told by other characters that Fabio has no substance, that he's only good in bed and has nothing else to offer anyone. Lukas senses there is more to Fabio than that, and it is confirmed for us when we see Fabio's tender, caring side as he attends to his parents' needs.
The scene is also a reflection on Lukas because it shows that people are not always on the inside how they may appear to others on the outside. Lukas may have been physically female on the outside, but he was as much a man as any other naturally born man on the inside.
These two were destined to find each other.
