Was scrolling through some comments on the mighty Hans and a few things sprung to mind on his origins etc..
He mentioned on the rig maybe implying he was in prison.
Also lots of people originally thought his surname was Hands or Hans was a nickname but in the episode where Jeremy tries to drown (cant remember her name) he mentions the Twins and the age in German.
Hans is a German surname so maybe he was born in Germany or lived there for a while where the Twins now live.
He also mentioned people like coldplay and voted for the Nazis, long shot but could tie back to his heritage.
