Well, it's a long story but if you want to know.

I worked as an officer of the LAPD SWAT division for five years with my partner Jim. In a bank robbery, I disobeyed orders from my superiors in order to save a hostage. So I got kicked off the team. Then I spiraled into a world of anger, in which I tried to help a criminal escape arrest. And when Jim and his team caught me, I got into a fist fight with Jim and he won. I got my neck snapped and then I wsa run over by a train and I woke up here.

Told you it was complicated
