Hmmm... For number 3, you forgot to mention the part where it hurts like hell for the next four weeks as the thorns grow back, costing you 4 dice in everything you do for the whole time. You could, however, find a freaky girlfriend with some kind of regeneration power or healing magic who enjoys it a little rough...
I would think that most of your contacts would somewhat freak out (as well as pretty much anyone else you'll ever see anywhere you go) and try to avoid you as much as possible, complicating your social life, obviously, but also your professional life as legwork becomes more complicated due to your newly-acquired freakiness. Oh! They still talk to you... most of them, anyways. But things are definitely not the way they used to be in the good old days when you were just another big troll with a HMG.
