Theory:SJA television discontinuity and plot holes/The Mark of the Berserker

From Tardis Wiki, the free Doctor Who reference
You are exploring the Discontinuity Index, a place where any details or rumours about unreleased stories are forbidden.
Please discuss only those whole stories which have already been released, and obey our spoiler policy.

This page is for discussing the ways in which The Mark of the Berserker doesn't fit well with other DWU narratives. You can also talk about the plot holes that render its own, internal narrative confusing.

Remember, this is a forum, so civil discussion is encouraged. However, please do not sign your posts. Also, keep all posts about the same continuity error under the same bullet point. You can add a new point by typing:

* This is point one.
::This is a counter-argument to point one.
:::This is a counter-argument to the counter-argument above
* This is point two.
::Explanation of point two.
::Further discussion and query of point two.

... and so on. 

Where has the red flashing light on Mr Smith's screen cover come from? It's never been there before.

Either it hasn't flashed in the right situation before;
Or it was 'installed' after mr smith rebooted;
Or Both!

Wouldn't it be better to destroy the pendant or lock it somewhere safe instead of throw it into shallow water where it could easily be found again?

Maybe this was done on purpose... I hope we will see a Doctor Who episode where somebody finds it!

Wouldn't Clyde's command to his mother to forget everything that's happened have just worn off after he discarded the pendant?
