The core conceit of this plot is the predatort lesbian trope, and that's not helped by the transphobic joke that comes from out of nowhere.

Unfortunately I do like gay characters with problems. Lesbian situationship so bad one of you has to get forcefully teleported into a star

An odd episode, but it has a very interesting hook. I like the idea of a pendant that can allow you to hear people's thoughts. I think that's such an interesting premise, and they really use this to explore character dynamics. Pace is slow though.

The story itself is pretty decent, but on principle, I have to give this story a 1/10 for being overtly transphobic for no reason whatsoever.
This, for me, is one of the case studies as to how bigotry affects your reasoning skills, because the transphobic writer of this story made Captain Jack Harkness of all people, the openly omnisexual man from the 51st century, have a problem with trans people. Not the rapist. Not the police officer. Not the slightly withdrawn, quite traditional woman. Captain Jack Harkness, which on its own doesn't pass the smell test, but then puts it down to him not being able to trust his friend because she realized something about herself???
Ridiculous, callous, horrible, terrible.

1/10.

Greeks Bearing Gifts is a Tosh focused episode, and I have to say I was largely checked out by the events of this one. The effects don't look great, the plot is meandering, and it not only does Tosh a bit of a disservice but overly playing up her submissiveness while at the cost of making the rest of the cast truly treat her like garbage. The plot doesn't really go anywhere and this episode is easily best forgotten as yet another dud chapter of Torchwood.
