Summary
This is a silly little crossover fic that would not leave me alone after I binged all of White Collar, so here you go.
Basically, Spencer and Neal had a little more than a one-night stand when Spencer was working on his first PhD and just before Neal went to New York. After not seeing each other in years, they reunite by chance because there's a combination art heist and murder investigation in New York that the White Collar division and BAU must work together on. Spencer and Neal end up having to go undercover as a couple, and realize that what happens in Vegas doesn't actually have to stay in Vegas. -

Summary
Stiles has a good life. He has a great job, a great husband, and he's happy in Virginia. The pack is doing fine under Scott's leadership back in California. Aside from the grisly murder scenes he sees on cases, Stiles' life is actually pretty perfect. Which is of course, when everything goes wrong.
Basically Stiles is part of the BAU team, and the Nogitsune returns. Mind games ensue. There are not nearly enough crossovers where Stiles is on the team, so idk here you go, brought to you by the voices in my head. Also in this fic Stiles and Derek didn't get together until Stiles was well into college, because I think canon-era Stiles/Derek is really creepy.

Summary
After magic is revealed to the world and Arthur's close brush with death, he and Merlin go into hiding. Merlin wishes that he could ignore the world and focus on him and Arthur, and finding Iris (who vanished just like they did) but being Emrys comes with a certain amount of responsibility to the magical peoples of the world. He just wants Arthur to be safe, but unfortunately Arthur has a habit of sticking his nose directly into danger without any regard for his own safety, and dying did not change that.
At least it seems like it won't be just the two of them against the world. Merlin doesn't understand how, but Arthur isn't the only one who's returned from the dead.

But when bodies start turning up with alarming similarities to things in Merlin's life, he dares to start hoping, that maybe, maybe it was time for Arthur's return. But is it the right time, and is Merlin willing to give everything up to save the world again?
