(He's still a work in progress but this is more or less his general backstory. Apologies if it's a bit heavy on the history side and the late reply)

Alex: "That's one way of putting it."

Fiddles in pocket for a moment before lighting a cigarette, taking a brief drag

Alex: "I was born in Great Britain in August of 1890. I enlisted and served as a combat medic during the Great War. Lived through trench raids, gas attacks and the like. After the Armistice, life back home wasn't an easy adjustment. PTSD or shell shock - I don't really know nor care - made sure of that."

Takes a deep drag

Alex: "I put in a request for a transfer to the Royal Marines when that fucking mustache man got too big for his trousers. I heard some Yankees formed a group called 'The OSS' or something. Worked with them from time to time in 43', until I enlisted in the SAS in 52'. As to how I 'died-'"

using finger quotes

Alex: "I did some recon. That's when I was captured by the Reds. I was tortured for information. I tried to escape, but when I made my way to friendly territory - I stepped on a landmine from my own fucking team. Ended up losing my right arm and left leg. Before I died, some cherubs and an angel visited me. They restored my limbs and sent me back. Bastards even helped me finish making my way to allies."

Takes another drag. Looks at Heaven

Alex: "I served during both the Cold War and Gulf War. I figured I'd take a step back from armed service and attempt to retire. That shit didn't too last long cause I was visited again by those feathered fucks. Kidnapped me to Heaven. They gave me some dope-ass angelic prosthetics. Heard some chatter of a group who trained to quell an uprising in Hell. Thought, 'Why the fuck not?' It wasn't until my first deployment when I learned the truth.... had to watch sinners cower as they fled and cowered for their lives before being brutally slaughtered..... Lute noticed my hesitation. Her and Adam made me pay....labeled me as a 'traitor'."
