Smoking a pack a day, and drinking throughout the night, Lornes bad habits are just as bad as his ability to not screw someone over to make a quick couple of credits to pay for more cigarettes.
Lorne and his brother, Mack, lost their parents when they were young. Having to fend for themselves early on, they learned quickly that this place chews up the weak and spits out the dead. They had to learn fast to make it here, Lorne found himself doing scammy deals and gambling to make due.
Of course, he always seems to find himself in situations he didn't have to be in. Conning the wrong gang or rigging a game of dice. It seems like he is in his own way of getting put onto a proper path where he can actually enjoy life.
