That was an OK finale.
I’m of two minds about the resolution with Ruby’s mum. On one hand, there being no significance at all is a bit of a let down, but on the other hand when dealing with gods, the whole point of the power is the belief, and that explanation does tie everything up fairly neatly. (not sure why ruby kept snowing though). Seeing her get back together with her mum was a nice send off.
Getting rid of sutek by throwing him off into the vortex, and having that undo everything was a bit iffy for me. There’s not been an established precedent that throwing someone into the time vortex undoes every action they ever did, and surely if that were the case that leads to a paradox?
Lots of call backs to past DW. Including the trend that at the end of the season every single person in the universe dies. But I guess that is the risk when you have a show that’s gone on for so long, once you’ve pushed the limits of danger to the max, there’s not really any way to escalate the tension further.
I misread that as prefix and, honestly, forthwhence doesn’t sound half bad.
