Frankly, I hadn't even realized that he was gay. A security guard (played by Connor Calland) confronted a Dalek-controlled character (played by Charlotte Ritchie from "Call the Midwife") at a secure facility. She asked him who can unlock the fingerprint lock. He replied, "Today, just me. Most secure digits in Yorkshire. That's what I tell my boyfriend, anyway. I probably shouldn't be telling you that, I'm new at this." She then killed him off-camera and used his lifeless hand to unlock the room that she needed to get into.
Now people are complaining on social media that this nameless security guard is the "most blatant bury your gays trope moment ever!" I even got into a brief argument with one of my exes over this situation. I mean, God forbid that I discuss the topic on his FB page after he posted on article about this.
"Doctor Who" and its various spin-offs have featured all sorts of LGBTQ characters over the past decade plus. Captain Jack. Ianto. Madame Vastra. Jenny. Bill Potts. They have features dozens of incidental queer characters, including a pregnant man in a recent episode who happened to be one of the few surviving characters in his own story.
So I look at this otherwise disposable character and find out that they gave him a boyfriend and I think, "that's interesting." I mean, who's grieving the numerous soldiers who were subsequently killed later in that episode by the Dalek who were never even given any back stories, queer or otherwise?
In other words, I don't think that this nameless security guard's death is worth getting upset over. Just don't say that in front of my ex-boyfriend...
