Doctor Who: “Face the Raven”
(Episode 9.10)

Well, we probably all knew this was coming sooner or later. It doesn’t make it any easier to swallow.
As is the case with Doctor Who, all good things must eventually come to an end. “Face the Raven” proves to be many things over the course of its hour run—the return of old allies, the exploration of a new world cleverly hidden amidst our own, the kickoff to an epic season concluder, etc. What it all boils down to, however, is this—“Face the Raven” is Clara Oswald’s (for now) departure episode. I say “for now,” because I’m positive Clara’s story will have some sort of epilogue that will coincide with the season finale. That being said, what this episode makes explicitly clear is that she is no longer in the land of the living.
With one or two exceptions (Susan, Sarah Jane), companion departures were rarely given any kind of dramatic weight in the classic series. The revised series has changed this, sending off companions in ways that have been emotionally lacerating (Amy/Rory), appropriately melodramatic (Rose), dramatically infuriating (Donna) and “eh, guess it’s time for me to leave now” (Martha). Clara’s demise fits comfortably in that first category. Even if it’s not the last we see of her, the experience leaves a scar, man. Unlike with the others, it’s not until halfway through the hour that one begin to recognize that the chess pieces are being put in place to knock Clara off the board.
Appropriately, the episode opens with The Doctor and Clara arriving in the TARDIS, having just completed yet another time adventure. How exactly Clara managed to get them banned from “the second most beautiful garden in all of time and space” will never be explained because their conversation is interrupted by a ringing TARDIS phone. The caller is Rigsy, the affable graffiti artist who the duo teamed up with back in last season’s highlight episode, “Flatline.” Rigsy is concerned, because he woke up with no memory of where he was for all of the day before. What’s more, there’s a tattoo on the back of his neck that is counting down to zero with each passing minute. Upon inspecting this strange phenomenon, The Doctor recognizes it as being 1.) alien in nature, and 2.) deadly. With Rigsy now having a wife and baby girl to think about, The Doctor takes on his case and the team goes about trying to locate a hidden alien community that might indicate the tattoo’s origins.
One of Doctor Who’s best qualities has been its ability to spin fairly mundane objects and occurrences into something distinctly alien (i.e. The Weeping Angels). Here, The Doctor indicates that Londoners pass a street leading into an alien realm everyday but that, because of a built-in misdirection system, passer-bys either ignore it, or forget what they’ve seen. The trio eventually locates a (Harry Potter reference alert) Diagon Alley-type street filled with a various assortment of aliens. What’s more, their mayor is none other than Ashildr, who both placed the tattoo (or “chronolock”) on Rigsy’s body and wiped his memory. The reason? He has been convicted of murdering a local alien named Anna. Specifically, he was found standing over her dead body. Taking a cue from the street’s security system, “misdirection” is a key word here, since the episode is all about leading the audience into what appears to be an alien-themed murder-mystery, only to have the rug pulled out from under them in the final third.
Naturally, The Doctor and Clara both believe that Rigsy is being set-up, and that he was simply at the wrong place at the wrong time. Ashildr is inclined to believe them, but herein lies one of the great wrinkles that makes Doctor Who’s world-building second-to-none—the residents need an outsider to be responsible for this mess, otherwise, everyone will be looking at their neighbors with suspicion and the carefully cultivated community will collapse into chaos. Right now, the fear of the malevolent “quantum shade,” which takes the form of a raven and kills anyone with a chronolock that reaches zero, is the only thing keeping everyone in check. As a demonstration of the region’s harsh laws, one elderly man is put to death for merely stealing medical supplies for his ailing wife.
While The Doctor interrogates the locals, Clara comes up with a possible strategy based on the fact that the executed man’s wife had begged him to pass along the chronolock tattoo to her. Apparently, someone afflicted with the tattoo can pass it along to a willing new host. Thinking like The Doctor, Clara develops a plan: Rigsy will pass along the chronolock to her and, because Ashildr has guaranteed that no harm will befall her, it will buy them time to prove Rigsy’s innocence. At first, Rigsy refuses to put Clara in danger, but he’s quickly reminded that he has a wife and daughter to think about and promptly goes along with the plan.
