I disagree about your point. In my opinion Kiera wasn't representation, it was tokenism.

No it's not. Specifically because they are characters who actually have had a storyline within a series that built up their characterisation and stories.

There's a credible reason to speak out about the one queer character of colour introduced to be killed off to benefit the story of a white character.

Eliot is great but guess what; he's a white dude.. just like the countless number of gay men being included in ensembles to fit the 'diversity quota'. As a queer POC… I appreciate he's there.. but I'm also painfully aware me having to force my viewpoint to relate to a white gay man.. again.
