Theory:SJA television discontinuity and plot holes/The Vault of Secrets

From Tardis Wiki, the free Doctor Who reference
If you'd like to talk about narrative problems with this story — like plot holes and things that seem to contradict other stories — please go to this episode's discontinuity discussion.
  • How did Androvax escape the Judoon?
He's a master criminal with the ability to possess the body of others. It's doubtful the Judoon could keep him there if he was determined enough.
  • Why was Androvax simply placed into prison? The Judoon executed a Plasmavore on the spot for taking a single life, yet Androvax, destroyer of over 14 planets, was sentenced to imprisonment rather then execution.
It could be that the Shadow Proclamation has laws against executing the last of a species.
  • The Men in Black seen in these episodes differ from those in Dreamland.
    • Mr Dread had White/Blonde hair in Dreamland but this Mr Dread has brown hair.
    • The guns in Dreamland fold out in the right arm but the guns here have the hand pop off to reveal the gun which comes out of the left hand.
    • In Dreamland there are 4 members of the Alliance of Shades but here there are only 3.
These are likely different, more advanced Men in Black, the Mister Dread from Dreamland was destroyed so the one in this episode is likely a replacement.
Not to mention over forty years have passed. It's safe to assume some modification took place.
