Liam

During his early teens, he was always a wild one and was extremely naive and acted on impulse a lot of the time. During one outing, he seen that the US Army were recruiting so he put his name down. He was a Private in the army when the bombs fell, and he fled into the vault with his family.

Now he's emerged, he is still pretty much the same person he was 200 years ago - a naive 23 year old just along for the ride. He's a drifter, he roams around with makeshift weapons, living in the dirt, taking the odd chem or two, and does as he pleases. He's met the 'Railroad' and basically, he's tagging along for the ride, not truly knowing what they're about. He's aware of synths, but doesn't really have an opinion on them. He's not dedicated as such to the Railroad, but he's with them because he has shelter, food and a place to hang.

During a scavenging trip, Liam will encounter the BoS's radio broadcoast for all units to regroup at the Police Station. He will venture there and just go with the flow, the BoS unknown he is not a real recruit. He'll board the Prydwen, be amazed at the marvel of engineering, and learn the history of the BoS. It will be at this point Liam discovers what the BoS really are, and will be ready to undergo their training and follow their ideologies.

(Tbh, I'm just taking my third playthrough a bit slow. Messing around with settlement building, exploration etc. I've met the Railroad, but just hanging with them for a while for some quest XP and stuff. Once I encounter the BoS, I shall join them)
