Weeeellllll, I dunno how much about my life back home you really know? But given I'm effing fictional, I guess it really isn't such a thing to explain it, even though back there, talking about my job? Kind of a "I can tell you, but then I'd have to kill you" thing...
Anyway. Rambling. My brother was trapped between dimensions thanks to an experiment at Warehouse 13. I started tracking huge and unexplained energy sources and found the Warehouse...nickname came from the message I left letting them know I hacked their system. "Knock knock". In the end, I basically got my job cause it was better for me to be on the inside than risk me blabbing Warehouse secrets on the outside.
But yes. It's not really a funny story or anything. But I still dig the nickname.
