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
“We didn’t have that in my day.”
“What?” Aaron asks, eyeing him curiously.
“A media liaison. A jet. A gay couple in the bullpen.” Rossi laughs under his breath, looking down at the desks below.
Aaron blinks. “I’m sorry, Dave… what?”
“A gay couple,” Rossi repeats, gesturing lazily at the bullpen. “The two young men down there currently sharing a desk.”
“Reid and Morgan?” Aaron’s voice goes up half an octave. Rossi isn’t sure he’s ever heard him sound so scandalized.
Rossi joins the BAU and notices some curiosities within the team.

Summary
Peter Parker isn’t allowed to go on his school’s mandatory field trip, and for once, that’s a good thing.
A full day at Stark Tower means uninterrupted lab time, finishing his first real piece of tech, and absolutely no Flash Thompson.
Unfortunately, it also means his entire class accidentally discovering that Peter Parker works for Tony Stark.

Summary
What if during the events before and after Monroe and Rosalee's wedding this happened instead?
Instead of Adalind sleeping with Nick she convinced Juliette to take the modified anti Grimm potion thingy….she agrees thinking it would be better for them if Nick wasn't a Grimm. The events lead to them breaking up when it gets revealed.
What if the cure for Nick losing his Grimm abilities was his boss…unfortunately it has some unforeseen consequences… Mpreg shenanigans and more ensue.
Or
Juliette wanted a normal life, and Adalind gave her the means to take it. But stripping Nick of his Grimm status doesn't stop the Wesen world from knocking on his door—and it certainly doesn't stop the Royal families from sending assassins to Portland or stop the unrelated line of duty drama from hunting him down.
Or
Where Nick really wishes his cop life and his Grimm life would stop intercepting.

Summary
"There are rules to being a superhero," Natasha tells Peter.
Most of the rules are common sense. Stay off the fan sites. Don't fall in love with civilians. Don't burn bridges just to toast marshmallows over the flames. And, most importantly, don't go to war with the media.
It's a pity that common sense isn't one of Peter's virtues.
OR: Peter goes to war with the media, because he's never been good at following rules.
