Can You Hear Me Screaming "Please Don't Leave Me"? by Keircat

Summary
The drugs flooding his system after a particularly hard case and going a little too long without a hit fills Spencer with immediate relief. If only he knew this was a high he might never come down from, he might've made a different choice.
Derek just wanted to check on Reid. He knew his friend wasn't as ok as he claimed he was, and this was a hard case. He never imagined just how badly Reid was struggling. Nor did he imagine the scene he'd walk into, the one he knew would forever be seared into his brain, even without an eidetic memory.

Summary
Dr Spencer Reid died 9 years ago, in a case gone wrong. He was Gideon's prodigy agent and was heading towards a fantastic career within the bureau. Instead, he ended up buried at the age of 23. Unable to come to terms with his sudden death and unfinished life, Reid still roams the halls of the FBI building, unseen and unnoticed. That is until a spiritual and already death-crossed Garcia stumbles upon him, and in her haste doesn't question the young doctor's presence. Her unmoving belief in Reid allows her not only to touch him but to open the eyes of others. The young doctor is soon dragged right back into the arms of the BAU, nursing the secret of what he is and trying to avoid questions of why Rossi, one of his colleagues, never seems to acknowledge him.

Somewhat bittersweet ending, at least imo, because of Spencer being a ghost, but it is happy too, in its own way. I want to hug Spencer tightly tho. This poor, poor baby died so young😭
Lots of cute moments tho. Spencer & Garcia friendship is perfect (even if Garcia is dumb for short bit) Morgan being a big brother even though they're technically the same age hehe. Rossi was the best tho omg. He was so protective of Reid and the reunion was so sweet.
