Underground hospital record

I wake with a start. I realize that I’ve been sleeping in the library. I quickly get up to put all the books and reports away, when a brown paper fall out of the stack. What’s this? I didn’t notice it eariler. I pick it up, and I realize it is an old hospital record from the Underground. Some parts are smudged and others are illegible, but I could make out a few words.

…unknown age, looks relatively young… place of residence is not known… no previous medical records… possibly not an Undergrounder… impossible… bump on head… miraculous recovery… no signs or symptoms of concussion… 

I didn’t know what to make of this record, but one thing is for sure; there is definitely more to our history than we were taught to believe.
