Yeah, it was good. Orphan Black is a great show. My only concerns are that Tony was such a douche and that his inclusion this late in the season seemed, thus far, peripheral to the overall story and a bit token. But then I guess clone Rachel, very central to Season 2, wasn't introduced until the end of Season 1 and portrayed as a real cow. So what do I know!
Some nice realisms included: he wears a packer (binding or or top surgery, evident but not discussed), is gay (or bi), injects T, everyone uses the right pronouns. He had long hair, and I know there's nothing wrong with that (have a trans guy friend who wears his hair very long) but it just made Tony look a bit too much like clone Sarah and it kept bumping me out of the buy into of the reality of it.
Overall though I thought it was a great inclusion of a trans character.
