Wrapped in the Wings of the Raven

A well known captain of a state of the art starship finds himself in a massive facility after having undergone experimentation and with a lapse of memory of how and why he is there, he makes a friend with a potentially deadly entity, SCP 049 who seems captivated by the ghost. That fascination soon turns into infatuation, the doctor having the first visitor whose immune to his lethal touch he finds out just how much he's needed someone like this. The doctor will eventually help Jason get back to where he belongs, and possibly come with him.

(Possible mature content to come in later chapters)
Also disclaimer - 049 is a bit headcanon here since; guilty as charged, I have not played the game yet I just really like what I've read on it so far. So if you see that he is out of character or not canon, just know I am taking a bit of artistic freedom in with me.
