we'll have an adventure, and several long trips
He trains his voice and saw a vocal coach.
Puberty blockers don't change vocal chord size, even if they block or reduce most effects of male puberty. Vocal chords grow no matter what.
If you take a look at his Adam's apple, you can tell that his real, untrained voice is much deeper.
I'm not saying his voice doesn't sound exaggerated and put on, much like the rest of his woman outfit, but it lacks a certain depth, something that I've not yet heard voice training alone achieve.
Just want to add as well that I thoroughly enjoyed the OP & updates, very well written!
