Mafia 83. Doctor Who: Aliens in London

I think Ment is definitely the mastermind, because there's no Mastermind role in the game, based on the description.

It seems like this is the case. If he gets out of the hospital tomorrow, we can send him back there.
But for now, I'd like to solve the clue. Does anyone have any ideas? I can't seem to figure it out. What is meant by "exile to London"? During World War II, London was home to the governments in exile of countries occupied by Germany, including Poland and Norway, and possibly others. General Charles de Gaulle flew to London after the defeat of France. There was also the evacuation of British and French troops to England, the Dunkirk operation in 1940. I couldn't find any date coincidences based on the forum registration dates. I don't know how else to connect it to the profile. Are there any other peaceful players left besides me? ) Let's help each other out.

And yes, a cyber-human killed someone today, so the Mafia should also eliminate competitors from the "Guests from Space" faction. Or can you only block? Don't hesitate, come forward. )
