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.

Brains Over Brawn, Any Day by stars_and_selkies
Fandoms: Criminal Minds (US TV), iZombie (TV)
06 Dec 2020

Summary
When the SUV explodes in a brilliant shower of glass, twisted metal, fire, and blood, Spencer Reid is technically DOA. He dies, he gets punctured in the stomach with a large piece of metal and hits his head on the sidewalk, and bleeds out before Hotch can even try to fix it.
Only, he wakes up right as Derek Morgan arrives on scene, and everything the BAU thought they knew about life and death is thrown out the window.
And one more thing; he has an insatiable craving for human brains.

Bookmarker's Notes
I just. FUCKING YES. just yes. I love this. I'm giggling like a maniac about it.i have seen not even all of s1 of iZombie but I know enough to absolutely love this.
Blonde Spencer is already so cursed (we've seen blonde MGG) and the fact he's now bleach blonde bc of being a zombie just AH. Hehehehe. RIP Spencer's brown hair.
I wonder how Amplification would go now with zombie Spencer?

What Makes Eternity Worth Living by MonPetitTresor for SpencerRemyLvr
Fandoms: Criminal Minds, Supernatural
11 Dec 2016
Tags
Summary
Thanks to a curse placed on him long ago, the man now known as Spencer Reid has lived countless lifetimes, forced to live while unable to ever truly die. He’s lived through famines and wars, through pestilence and plagues. He’s lived and he’s loved – deeply and irrevocably. And he has also lost. He’s known the pain of losing those that become like family, as well as those that become so much more. For a long while the pain of it hardened him, pushing him to lock himself away so that he couldn’t be hurt again. That is, until the day that he crossed paths with a woman and child who changed his life forever.
Now he’s here, working at the FBI’s Behavioral Analysis Unit with a group of people who have become like family to him. They don’t know his secret and he’d much prefer to keep it that way. This is the closest that he’s let anyone in years... until the day he runs into someone from his past, someone he didn’t expect to ever see again.
Now suddenly Spencer's peaceful little world is being tossed upside down by the presence of one feisty little archangel who seems determined to break down every single wall that Spencer's built around himself to keep his heart safe.

Summary
Dr. Spencer Reid was a lot of things. A genius with an IQ of 187, someone with eidetic memory, a great friend, someone who managed to be banned from every casino in Las Vegas. But one thing he was, that nobody knew, was a witch.
Or
Five times Spencer Reid used his magic to help the team + One time he had to come clean.
