Two seasons in a row we saw a BLACK companion get converted into a Cyberman and given a strange send-off. The first, Danny Pink, was supposed to be Clara Oswin's love interest -- we even saw them rescue an apparent descendent of that match-up, until Moffatt needed someone to be converted into a Cyberman. Then in Season 10, we had Bill Potts, an excellent companion, get converted into a Cyberman because Moffatt needed someone to be converted into a Cyberman. The history of Doctor Who has not seen a successful conversion of a Companion into a Cyberman until Danny Pink. With Bill Potts we have a second successful Companion-Cyberman-conversion. What's the commonality? Both the actors are BLACK?
I was going to let this pass -- until todays news included Moffatt bragging about the story twist in The Doctor Falls of having Bill Potts saved by her love interest, Heather. Ugh. Really? It's all okay because you gave yourself a magic way out of the corner you wrote yourself into?
No matter how brilliant Moffatt is in coming up with clever stories -- this shows a weakness in that he writes himself into corners, and rather than face the consequences of the story he's penned, Moffatt comes up with a magic way out.
