looking for odd crossovers and long crossovers

[angelzfurys.livejournal.com]

Hi, I am looking for any and all crossovers that may be for older shows or an odd crossover like...

Quantum leap
The Pretender
The Sentinel
Prey
Warehouse 13
The Dead Zone
Heroes
Person of Interest
Merlin
Grimm

or any good long crossovers from Harry Potter, Law and Order, Criminal Minds, NCIS ext.

Any gene, pairing, theme, AU, canon, or whatever I would be happy to read. Thank you all a million times who responds to my search.


Oh...I am a total idiot for not saving the link but does anyone know of a Person of Interest crossover I think it was called 'Not Him Again?'

Mods sorry if I got any tags wrong or the mass tagging.
