This show seems very keen on using forgetting stuff as a way of not dealing with the consequences of events. So we've killed off Rory, and wiped it from Amy's mind so that she can carry on next week as if nothing had happened. So... what was the point of him existing in the first place again? A totally inconsequential character death with little or no emotional impact at all. And how does Rory never having existed fit with the timeline of the last couple of episodes in which he played a role in the plot, and which needed to happen to get to this point?
I don't understand how anyone could watch that and come to that conclusion? Why is it difficult to see this is simply another beat in a series long storyline?
Is the modern audience really so mentally slow they need obvious things spelling out to them?
